The potential effects of Caper (Capparis spinosa L.) in the treatment of diabetic neuropathy

Diabetic neuropathy(DN)is the most common form of neuropathy worldwide,with its prevalence rising alongside diabetes,and being characterized by sensory,motor or autonomic symptoms.DN is considered to be an incurable complication of diabetes,the management of which mainly consists of improving glycemic control,managing pain relief and ensuring continuous foot care.Although gabapentin,duloxetine and tricyclic antidepressants are commonly used to reduce patient symptoms,they do not affect the pathophysiology and progression of neuropathy.Furthermore,these drugs can have various side effects including insomnia,decreased appetite,arrhythmia,heart failure,and suicidal behavior.According to traditional Persian medicine,DN is recognized as a type of“Khadar”or“Esterkha”(a sensory or motor disorder,respectively)that occurs due to the accumulation of sugars in the peripheral nerves.Capparis spinosa L.,commonly known as the caper plant,has been recommended in authentic sources of traditional Persian medicine to treat such disorders.In this study,we reviewed the pharmacological properties of C.spinosa using the Web of Science,PubMed,Scopus and Google Scholar databases,and found that Capparis spinosa L.could affect several pathways involved in DN pathogenesis,including aldose reductase activity,the secretion of inflammatory mediators(IL-17,TNF-α,IL-1β,IL-6),oxidative stress,hyperlipidemia,hyperglycemia and advanced glycation end product formation.Based on these findings,we hypothesize that Capparis spinosa L.,may prevent the progression and reduce the symptoms of diabetic neuropathy,and so can be considered as a complementary treatment in this disorder.This hypothesis should be evaluated in well-designed in vitro and in vivo studies,and through clinical trials.

Capparis spinosa L waste activated carbon as an efficient adsorbent for crystal violet toxic dye removal: Modeling, optimization by experimental design, and ecological analysis

Textile dyes are dramatic sources of pollution and non-aesthetic disturbance of aquatic life and therefore represent a potential risk of bioaccumulation that can affect living species.It is imperative to reduce or eliminate these dyes from liquid effluents with innovative biomaterials and methods.Therefore,this research aims to highlight the performance of Capparis spinosa L waste-activated carbon(CSLW-AC)adsorbent to remove crystal violet(CV)from an aqueous solution.The mechanism of CV adsorption on CSLW-AC was evaluated based on the coupling of experimental data and different characterization techniques.The efficiency of the CSLW-AC material reflected by the equilibrium adsorption capacity of CV could reach more than 195.671 mg·g^(–1) when 0.5 g·L^(–1) of CSLW-AC(Particle size≤250μm)is introduced into the CV of initial concentration of 100 mg·L^(–1) at pH 6 and temperature 65℃ and in the presence of potassium ions after 60 min of contact time according to the one parameter at a time studies.The adsorption behavior of CV on CSLW-AC was found to be consistent with the pseudo-second-order kinetic model and Frumkin's linear isothermal model.The thermodynamic aspects indicate that the process is physical,spontaneous,and endothermic.The optimization of the process by the Box Behnken design of experiments resulted in an adsorption capacity approaching 183.544 mg·g^(–1)([CV]=100 mg·L^(–1) and[CSLW-AC]=0.5 g·L^(–1) at 35 min).The results of the Lactuca sativa seeds germination in treated CV(70%),adsorbent solvent and thermal regeneration(more than 5 cycles),and process cost analysis(1.0484 USD·L^(–1))tests are encouraging and promising for future exploitations of the CSLW-AC material in different industrial fields.
