Quantitative trait loci identification reveals zinc finger protein CONSTANS-LIKE 4 as the key candidate gene of stigma color in watermelon(Citrullus lanatus)

Stigma color is a critical agronomic trait in watermelon that plays an important role in pollination.However,there are few reports on the regulation of stigma color in watermelon.In this study,a genetic analysis of the F2 population derived from ZXG1553(P1,with orange stigma)and W1-17(P2,with yellow stigma)indicated that stigma color is a quantitative trait and the orange stigma is recessive compared with the yellow stigma.Bulk segregant analysis sequencing(BSA-seq)revealed a 3.75 Mb segment on chromosome 6 that is related to stigma color.Also,a major stable effective QTL Clqsc6.1(QTL stigma color)was detected in two years between cleaved amplified polymorphic sequencing(CAPS)markers Chr06_8338913 and Chr06_9344593 spanning a~1.01 Mb interval that harbors 51 annotated genes.Cla97C06G117020(annotated as zinc finger protein CONSTANS-LIKE 4)was identified as the best candidate gene for the stigma color trait through RNA-seq,quantitative real-time PCR(qRT-PCR),and gene structure alignment analysis among the natural watermelon panel.The expression level of Cla97C06G117020 in the orange stigma accession was lower than in the yellow stigma accessions with a significant difference.A nonsynonymous SNP site of the Cla97C06G117020 coding region that causes amino acid variation was related to the stigma color variation among nine watermelon accessions according to their re-sequencing data.Stigma color formation is often related to carotenoids,and we also found that the expression trend of ClCHYB(annotated asβ-carotene hydroxylase)in the carotenoid metabolic pathway was consistent with Cla97C06G117020,and it was expressed in low amounts in the orange stigma accession.These data indicated that Cla97C06G117020 and ClCHYB may interact to form the stigma color.This study provides a theoretical basis for gene fine mapping and mechanisms for the regulation of stigma color in watermelon.

Analysis of the Effect of Intensive Nursing Care on Improving Sleep Quality During the Perioperative Period of Severed Finger Reimplantation

Objective:To investigate the clinical effect of perioperative intensive nursing on patients who underwent severed finger reimplantation and its influence on sleep quality.Methods:62 patients who underwent severed finger reimplantation between January 2023 and December 2023 were included.They were divided into two groups:the observation group(n=31)and the control group(n=31).The control group received basic nursing interventions,while the observation group received intensive nursing care.The comparison parameters included visual analog pain score(VAS),incidence of vascular crises,length of hospitalization,Pittsburgh Sleep Quality Index(PSQI),Hamilton Depression Score(HAM-D),Hamilton Anxiety Score(HAM-A),and patient satisfaction.Results:Postoperative VAS score,incidence of vascular crisis,hospitalization time,PSQI score,and HAM-A and HAM-D scores of the observation group were lower than those of the control group(P<0.05).Meanwhile,the patient satisfaction of the observation group was higher than that of the control group(P<0.05).Conclusion:Perioperative intensive nursing care for patients undergoing severed finger reimplantation demonstrates significant benefits.It reduces postoperative pain,lowers the incidence of vascular crises,shortens hospitalization durations,enhances sleep quality,alleviates negative emotions,and improves nursing satisfaction.These findings underscore the importance and applicability of such care practices.

Experimental Study of Multi-slice Spiral CT Perfusion Imaging in VX_ 2 Soft-tissue Tumor of Rabbits

An experimental animal model of malignant soft-tissue tumor was established to investigate the applied value of multi-slice spiral CT perfusion imaging preliminarily. Ten New Zealand white rabbits which were implanted with VX2 tumor in either proximal thigh were subjected to CT plain scan and perfusion scan two weeks later respectively, then the original perfusion images were transmitted to AW4.0 Workstation. The functional maps and perfusion parameters including blood flow （BF）, blood volume （BV）, mean transit time （MTT） and permeability surface （PS） were computed and analyzed. All the values of BF, BV and PS in VX2 soft-tissue tumors were obviously higher while the MTT-values were lower than those in the normal muscular tissues significantly. It was suggested that multi-slice spiral CT perfusion imaging is an accurate, convenient and relatively safe functional imaging technique, and can give a quantitative assessment to angiogenesis and blood perfusion of soft-tissue tumors.

Magnetic resonance imaging of soft-tissue tumors of the extremities: A practical approach

Diagnosis of extremity soft-tissue tumors can be challenging.Characteristics of tumor margins can help precisely identify locally aggressive or non-aggressive behavior for surgical planning,but cannot differentiate benign from malignant lesions.Most malignant tumors can have inhomogeneous signals on T2-weighted images.Although a uniform signal on T2-weighted images can be a reliable indication of a benign lesion,a well-defined mass with homogeneous internal signal intensity does not definitively identify a benign lesion.Some common and distinctive soft-tissue lesions can have specific clinical and imaging features allowing a diagnosis without biopsy.These are known as determinate lesions.This illustrative report presents a diagnostic guide for extremity soft-tissue tumors based on tissue signal and morphological characteristics on magnetic resonance images.It is important for clinicians to be familiar with the imaging characteristics of common determinate lesions.

Multimodality Treatment in Adult Patients with High-risk Soft-tissue Sarcomas

Objective： We enrolled retrospective data to determine the efficacy of combined chemotherapy and surgery for local tumour control and survival in patients with high-risk soft-tissue sarcomas. Methods： We collected data from 25 patients with high-risk soft-tissue sarcomas treated with four cycles of etoposide, ifosfamide and doxorubicin （EIA） followed by definitive surgery with or without postoperative radiotherapy and adjuvant chemotherapy. 21 patients received chemotherapy in a neoadjuvant/adjuvant clinical setting; eighteen of them completed adjuvant chemotherapy. Four patients received chemotherapy in an adjuvant setting only. Results： The objective response rate of neoadjuvant chemotherapy assessable in 21 patients was 43%. Including NED （n=7） and partial remissions （n=3）, the radiographic response rate was 47.6% with additional 42.9% stable diseases （n=9）. Surgery was performed in two patients before completing four neoadjuvant chemotherapy cycles because of disease progression. Median overall survival for all patients was 21.6＋ months. After completion of chemotherapy, in 62% of patients R0-resection could be performed. Conclusion： High proportion of R0-resections supports the idea of tumour down-staging after neoadjuvant treatment. Response to neoadjuvant chemotherapy is predictive for improved local tumour control resulting in long-term survival benefit.

Anterior glenohumeral instability:Current review with technical pearls and pitfalls of arthroscopic soft-tissue stabilization

The glenohumeral joint(GHJ)allows for a wide range of motion,but is also particularly vulnerable to episodes of instability.Anterior GHJ instability is especially frequent among young,athletic populations during contact sporting events.Many first time dislocators can be managed non-operatively with a period of immobilization and rehabilitation,however certain patient populations are at higher risk for recurrent instability and may require surgical intervention for adequate stabilization.Determination of the optimal treatment strategy should be made on a case-by-case basis while weighing both patient specific factors and injury patterns(i.e.,bone loss).The purpose of this review is to describe the relevant anatomical stabilizers of the GHJ,risk factors for recurrent instability including bony lesions,indications for arthroscopic vs open surgical management,clinical history and physical examination techniques,imaging modalities,and pearls/pitfalls of arthroscopic soft-tissue stabilization for anterior glenohumeral instability.

The Importance of the Multidisciplinary Approach to Surgical Treatment of Extremity Soft-Tissue Sarcomas

Soft tissue sarcomas (STS) are rare neoplasm with frequencies around 1% of all neoplasms. Although it consists of a high heterogeneous group of tumors, surgery is the mean treatment. The STS surgery is still challenging and complex procedure is usually required: this is because STS requires different types of resection and reconstruction due to various tissue-commitments (nerve, arteries, skin and muscle). So, a multidisciplinary team must be prepared for STS approach to obtain the maximum local control and a limited extremity functional impairment. We, here, showing our experience, wish to introduce some technical contrivances in STS surgery, with special reference to tissue reconstruction. This may illustrate the necessity of a multidisciplinary team approach in this surgery.

Nutritional Composition and Anti-Nutrient Levels in Raw and Processed Varieties of Finger Millet Promoted for Nutritional Security

Finger millet (FM) is rich in nutrients such as minerals, vitamins, and amino acids. However, the levels of nutrients and their bioaccessibility depend on the variety, the levels of ant nutrients, the chemical form of nutrients, and the type of processing methods used. The study determined the levels of selected nutrients, anti-nutrients, and bioaccessibility in raw and processed varieties of finger millet being developed by the Kenya Agricultural and Livestock Research Organization (KALRO) in Kenya. Raw finger millet seeds from KALRO Centers in Kenya were processed by malting for 60 hours and roasting at 110°C for 5 minutes as the optimal conditions. Levels of minerals were determined by AAS and AES, anti-nutrients by UV-visible spectrophotometer, proteins by the Pierce kit method, and vitamins by HPLC. The IE4115 and IE3779 showed the highest levels of nutrients and lowest levels of antinutrients hence preferred for processing and bioaccessibility studies. The level (mg/100 g) of selected minerals;K, Cr3+, Mg, Ca, P, Fe, and Zn were found to be highest in the following varieties of the FM;IE3779 (688.519 ± 1.57), IE 4115 (1.29 ± 0.07), IE4115 (294.38 ± 1.93), IE3779 (466.67 ± 4.17), IE4115 (250.92 ± 0.33), KERICHO P (16.98 ± 0.05) and IE4115 (64.10 ± 2.35) respectively. For β-carotene, vitamin B, B2, B3, B6 and B9 the levels were highest in the following varieties of FM;KAKW3 (0.023 ± 0.02), IE4115 (14.85 ± 0.16), IE4115 (12.998 ± 0.04), IE4115 (5.843 ± 0.07), IE3779 (0.06 ± 0.04) and KAKW4 (9.832 ± 0.08). Phytates, tannins, phenols, and oxalates were found to be lowest in the following varieties: IE3779 (14.20 ± 2.90, IE4115 (27.83 ± 0.73), NKFM1 (9.69 ± 0.07) and IE4115 (0.25 ± 0.01). The highest bioaccessibility values reported for K, Mg, Ca, P, Cr3+, Fe, and Zn were 89.53% (malting, IE3779), 49.28% (malting, IE4115), 60.41% (Malting, IE4115), 69.40% (malting, IE4115), 12.9% (malting, IE4115), 59.84% (malting, KAKW3) and 66.89% (roasting, IE3779) respectively (Table 8). For beta carotene, vitamin B1, B2, B3, B6 and B9 the values were 73.33% (malting, p224), 78.84% (malting, IE4115), 78.34 (malting, IE3779), 97.63% (malting, IE4115), 91.64% (malting, IE4115), and 77.52% (roasting, IE4115) (table The result on levels and bioaccessibility showed that IE4115 and IE3779 varieties were more nutritious and therefore should be promoted for nutritional security.

Investigation of Experimental Devices for Finger Active and Passive Tactile Friction Analysis

Complicated tribological behavior occurs when human fingers touch and perceive the surfaces of objects.In this process,people use their exploration style with different conditions,such as contact load,sliding speed,sliding direction,and angle of orientation between fingers and object surface consciously or unconsciously.This work addressed interlaboratory experimental devices for finger active and passive tactile friction analysis,showing two types of finger movement.In active sliding experiment,the participant slid their finger freely against the object surface,requiring the subject to control the motion conditions themselves.For passive sliding experiments,these motion conditions were adjusted by the device.Several analysis parameters,such as contact force,vibration acceleration signals,vibration magnitude,and fingerprint deformation were recorded simultaneously.Noticeable friction differences were observed when comparing active sliding and passive sliding.For passive sliding,stick-slip behavior occurred when sliding in the distal direction,evidenced by observing the friction force and the related deformation of the fingerprint ridges.The employed devices showed good repeatability and high reliability,which enriched the design of the experimental platform and provided guidance to the standardization research in the field of tactile friction.

Considerations for gluten free foods-pearl and finger millet processing and market demand

The market demand for gluten free foods is increasing due to frequent incidences of celiac disease and increasing awareness on consumption of gluten free foods.Millets have become the major constituent of diet as they are gluten-free and also excellent sources of micro and macro nutrients such as vitamins,minerals,dietary fibers and phenolic compounds.Among various millets,the finger millet and the pearl millet are the two most important and common millet varieties grown extensively.Since,they are regarded as the staple foods of the poor and vulnerable populations,development of new products and improvements in their nutritional quality will aid in the general health of these population.Processing of millets and production of variable gluten-free ready-to-eat and nutritional supplements has increased their market value in the recent years.Furthermore,processing can also help in shelf-life extension of the millets with nutritional enrichment,expanding its markets to non-traditional millet consumers.In this context,the present review is aimed to focus on the current processing methods to develop products from the two millet varieties that are gluten free and outline their nutritional benefits.

Biometric Finger Vein Recognition Using Evolutionary Algorithm with Deep Learning

In recent years,the demand for biometric-based human recog-nition methods has drastically increased to meet the privacy and security requirements.Palm prints,palm veins,finger veins,fingerprints,hand veins and other anatomic and behavioral features are utilized in the development of different biometric recognition techniques.Amongst the available biometric recognition techniques,Finger Vein Recognition(FVR)is a general technique that analyzes the patterns of finger veins to authenticate the individuals.Deep Learning(DL)-based techniques have gained immense attention in the recent years,since it accomplishes excellent outcomes in various challenging domains such as computer vision,speech detection and Natural Language Processing(NLP).This technique is a natural fit to overcome the ever-increasing biomet-ric detection problems and cell phone authentication issues in airport security techniques.The current study presents an Automated Biometric Finger Vein Recognition using Evolutionary Algorithm with Deep Learning(ABFVR-EADL)model.The presented ABFVR-EADL model aims to accomplish bio-metric recognition using the patterns of the finger veins.Initially,the presented ABFVR-EADL model employs the histogram equalization technique to pre-process the input images.For feature extraction,the Salp Swarm Algorithm(SSA)with Densely-connected Networks(DenseNet-201)model is exploited,showing the proposed method’s novelty.Finally,the Deep-Stacked Denoising Autoencoder(DSAE)is utilized for biometric recognition.The proposed ABFVR-EADL method was experimentally validated using the benchmark databases,and the outcomes confirmed the productive performance of the proposed ABFVR-EADL model over other DL models.

Finger compartment syndrome due to a high-pressure washer injury:A case report

BACKGROUND Although the finger compartment syndrome is not common,it compresses the neurovascular bundles in a limited space and blocks blood flow to the fingers,causing necrosis of the fingertips.Finger fasciotomy through unilateral or bilateral midline release of the finger can achieve decompression of the finger compartment.Herein,we report a case of the compartment syndrome in a finger injury caused by a high-pressure water flow which is commonly used in car washing stations.CASE SUMMARY A 60-year-old man injured his right middle finger while using a high-pressure washer at a car washing station.The patient complained of severe pain in his middle finger and a 0.2 cm punctured open wound on the volar side of the distal phalangeal joint of the middle finger.The fingertip was pale,numb,and characterized by severe swelling and a limited range of motion.Finger radiography showed that there was no fracture in the finger.Digital decompression was performed through finger fasciotomy by bilateral midline incision.On the second day after surgery,the color of the fingertip returned to pink,swelling was resolved,and the range of motion returned to normal.The sensation of the fingertip was completely restored,and the capillary refill test and pinprick test were positive.CONCLUSION The fingertip compartment syndrome can be caused by a high-pressure water flow damage to the fingers when using high-pressure washers at a car washing station.To avoid finger necrosis,rapid diagnosis of the finger compartment syndrome and appropriate digital decompression are essential to better outcome.

Prognostic role of ring finger and WD repeat domain 3 and immune cell infiltration in hepatocellular carcinoma

We have found that the expression of ring finger and WD repeat domain 3(RFWD3)is significantly higher in unpaired and paired hepatocellular carcinoma(HCC)tissues than in normal tissues.Moreover,this expression has a significant correlation with the infiltration level of 14 immune cell types and when the detected RFWD3 expression levels were grouped as high and low,a prominent difference was revealed for overall survival,disease-specific survival,and progression-free interval.Through statistical analysis(univariate Cox),we were also able to identify RFWD3 as an independent prognostic element for HCC,with RFWD3 having an ability to accurately predict HCC prognosis(area under the curve of 0.863).Finally,we have generated prognostic nomograms for probabilities of 1-,3-and 5-year overall survival in HCC via integrating the factors of age,pathologic stage,alpha-fetoprotein level,and RFWD3 expression.

Triggering,clicking,locking and crepitus of the finger:A comprehensive overview

Triggering,locking,clicking,and crepitus of the fingers are common symptoms patients present with.Even though crepitus and triggering can occur as part of the same underlying diagnosis,it is important to differentiate between them,as they usually indicate different possible diagnoses.The differential diagnoses that should be considered include trigger finger,metacarpophalangeal joint(MCPJ)arthritis,fractures or dislocations,extensor digitorum communis subluxation or dislocation,locked MCPJ,avascular necrosis of the metacarpal head,and Dupuytren’s disease.A thorough clinical examination with appropriate special investigations can permit the clinician to make the correct diagnosis.Appropriate management of a confirmed diagnosis is successful in providing symptomatic improvement.

The Effect of Modified Postoperative Treatment on Finger Replantation Survival Rate

Objective:To explore the clinical effect of modified treatment after finger replantation and its impact on the survival rate of replantation.Methods:The research was conducted from March 2022 to March 2023.A total of 58 patients who underwent finger replantation at our hospital were selected.These patients were divided into two groups using the digital table grouping method:the research group(n=29)and the control group(n=29).Patients in the control group received standard treatment following finger replantation,while patients in the study group received modified treatment after the procedure.The incidence of vascular crisis and the survival rate of replantation were compared between the two groups.Results:The incidence of vascular crisis in the study group was lower than that in the control group(P<0.05);the replantation survival rate in the study group was higher than that in the control group(P<0.05).Conclusion:Modified treatment after replantation of severed fingers can reduce the incidence of vascular crisis replantation and improve the survival rate of replantation,so it should be popularized and applied in medical institutions.
