Objective:In traditional medicine,stachys lavandulifolia or mountain tea has been used in the treatment of arthritis and rheumatoid arthritis.A leaf extract from this plant is also thought to be effective in treating epilepsy as well as other neurological ailments.To assess the effect of s.lavandulifolia extract(sLE),rats were exposed to a stress and anxiety model caused by seizures.Materials and Methods:A challenge dose of pentylenetetrazole(PTZ)(60 mg/kg)was used to induce seizures in male Wistar rats(200-250 g).Animal treated with an intraperitoneal injection of either sLE(50 mg/kg)or sodium valproate(100 mg/kg)alone or in combination 30 min before PTZ challenge.The effect of stress and anxiety was assessed using an open field test(OFT),forced swim test(FsT),and elevated plus maze(EPM).At the end of the experiment,anesthesia was used to euthanize rats,and their blood serum was collected for measurements of glutathione(GsH),malondialdehyde(MDA),and GsH peroxidase(GPx).Results:In contrast to the control group,those treated with PTZ exhibited depressive behavior.At 50 mg/kg,sLE provided protection against seizures induced by PTZ.sLE also reduced seizure-induced stress and anxiety,significantly improving FsT,EPM,and OFT compared with the PTZ-treated group.By decreasing MDA levels and restoring the antioxidant enzymes GsH and GPx,sLE treatment protects against seizure-induced anxiety and stress.Conclusions:sLE inhibits oxidative stress damage and seizure-induced stress by inhibiting seizures'inhibitory effects.

Objective: Nasal vestibular furunculosis (NVF) is characterized by an acute localized infection of the hair follicle in the skin lining of the nasal vestibule. This study provides an up-to-date narrative analysis on NVF, its presentation, complications and management.Methods: A literature search was conducted electronically with no time constraints using "Nasal Vestibular Furuncolosis" or "NVF" through Medline, Cochrane Library and Web of science, including MesH terms with no language restrictions. Included were: studies that described NVF’’s presentation and subsequent management and excluded were: Irrelevant studies that did not provide details about NVF’’s presentation or management, furthermore studies that alluded to Nasal vestibulitis without furunculosis were excluded. There were no limitations on time, up until the review was commenced in May 2020.Results: seven articles complied with the inclusion criteria. All papers reviewed were from 2015 to 2020. Three out of 4 studies reported duration of symptomatic NVF between 3 and 4 days. The most common presentation of NVF was reported as erythema, swelling, tender over the nasal tip. The most frequent, successful management of NVF frequently included intranasal topical mupirocin and in some cases oral sodium fusidate. NVF was reported to clear within 7 days by 2 studies. There were no randomised studies exploring NVF or NVF management.Conclusion: Although a very common condition, much research is required to allude to the pathophysiology and management of NVF. Future studies should explore the reasons as to the resistance of topical antibiotics in some patients, the differing strains ofstaphylococcus aureus and their resulting complications, the reasons behind the familiar connection and the most effective management plan for NVF.

The effect of presence of silver nanoparticles in pure N-methyl-2-pyrrolidone(NMP)solvent for ethylene gas absorption in an experimental pressure decaying setup has been investigated.All experiments were performed at temperatures of 278.15 K,298.15 K and 328.15 K and different pressures(up to ethylene dew point)as well as different concentrations of silver nanoparticles(0.05 g·L^(-1) and 0.1 g·L^(-1)).The kinetic data of absorption,Henry’s law constants,and heat of absorption were calculated.Comparison of the pure solvent and the nanofluids absorption results revealed that the presence of small amounts of nanoparticles could improve the absorption performance between 1.5%-18%.Finally,the effect of temperature,pressure,and nanoparticle concentration on the equilibrium results were investigated.

In this study some soil phosphorous sorption parameters(PsPs)by using different machine learning models(Cubist(Cu),random forest(RF),support vector machines(sVM)and Gaussian process regression(GPR))were predicted.The results showed that using the topographic attributes as the sole auxiliary variables was not adequate for predicting the PsPs.However,remote sensing data and its combination with soil properties were reliably used to predict PsPs(R^(2)=0.41 for MBC by RF model,R^(2)=0.49 for PBC by Cu model,R^(2)=0.37 for sPR by Cu model,and R^(2)=0.38 for sBC by RF model).The lowest RMsE values were obtained for MBC by RF model,PBC by sVM model,sPR by Cubist model and sBC by RF model.The results also showed that remote sensing data as the easily available datasets could reliably predict PsPs in the given study area.The outcomes of variable importance analysis revealed that among the soil properties cation exchange capacity(CEC)and clay content,and among the remote sensing indices B5/B7,Midindex,Coloration index,saturation index,and OsAVI were the most imperative factors for predicting PsPs.Further studies are recommended to use other proximally sensed data to improve PsPs prediction to precise decision-making throughout the landscape.

The nonlinear interactions of a microarch resonator with 3:1 internal resonance are studied.The microarch is subjected to a combination of direct current(DC)and alternating current(AC)electric voltages.Thin piezoelectric layers are thoroughly bonded on the top and bottom surfaces of the microarch.The piezoelectric actuation is not only used to modulate the stiffness and resonance frequency of the resonator but also to provide the suitable linear frequency ratio for the activation of the internal resonance.The size effect is incorporated by using the so-called modified strain gradient theory.The system is highly nonlinear due to the co-existence of the initial curvature,the mid-plane stretching resulting from clamped anchors,and the electrostatic excitation.The eigenvalue problem is solved to conduct a frequency analysis and identify the possible regions for activating the internal resonance.The effects of the piezoelectric actuation,the electric excitation,and the small-scale effect are investigated on the internal resonance.Exclusive nonlinear phenomena such as Hopf bifurcation and hysteresis are identified in the microarch response.It is shown that by applying appropriate piezoelectric actuation,one is able to activate microarch internal resonance regardless of the initial rise level of the microarch.It is also disclosed that among all the parameters,AC electric voltage has the greatest effect on the energy exchange between the interacting modes.The results can be used to design resonators and internal resonance based micro-electro-mechanical system(MEMs)energy harvesters.

In this paper,we use a Tsallis holographic dark energy model in two forms,interacting and noninteracting cases,to acquire some parameters as the equation of state for the energy density of the Tsallis model in the FRW Universe concerning the complex form of quintessence model.We will study the cosmology of complex quintessence by revamping the potential and investigating the scalar field dynamics.Then we analyze(w-w’)and stability in two cases,i.***.noninteracting and interacting.We will explore whether these cases describe a real Universe by calculating fractional energy densityΩ_(D)and concerning two parts of the quintessence field effect(complex and real part)by considering the real part of this field to be a slow-roll field.We know that the part in which the fractional energy density(Ω_(D)>1)does not describe a real Universe.Also,we specified an interacting coupling parameter b2that depends on the constant parameter of the Tsallis holographic model(δ)with respect to fractional energy density(0.73).Unlike independence between the fractional energy density and interacting coupling in the real quintessence model,we determine a relationship among these parameters in this theory.Finally,by plotting some figures,we specify the features of(w-w’)and(ν^(2)_(s))in two cases and compare the result with each other.

The synchronization and ovulatory responses of sangsari cross bred ewes and metabolism of energy substrates in 8-cell stage embryos to hatched blastocysts stage produced in vitro or in vivo were investigated. Ewes were assigned randomly to receive 37.5 IU of porcine follicle stimulating hormone （FsH-P） daily for the 3 days preceding implant removal （Day 0）. synchronization of estrus was carried out using a 1.5 mg norgestomet （Crestar） ear implant for ] 2 days. Ewes in estrus were mated two to three times with rams of proven fertility. At the time of first mating each ewe was administered 1000 IU of human chorionic gonadotrophin （hCG） to induce ovulation. surgical embryo recovery was performed on Days 4 and 6 after onset of estrus （Day 0） and recovered embryos were subjected to comparative metabolism studies with in vitro derived embryos at the same stage of development. The number of corpora lutea （CL）, unovulated follicles and overall ovarian activity were recorded for each ewe during the breeding and non-breeding seasons. While the pattern of oxidation was similar among in vitro and in vivo derived embryos, a low pyruvate to lactate ratio was the preferred substrate of embryos derived in vitro. A high level of production of C02 and lactate resulted from a stress response to the suboptimal culture environment. The first marked increase in the metabolism of glucose by ovine embryos was detected in compact morula stage, but there was no significant increase in the oxidation of glucose after the morula stage. Two different concentrations of glucose were compared, but this did not affect metabolism. However, the rate of incorporation and metabolism of glucose tended to be higher at the 0.56 mmol/L glucose dosage.

Groundwater contamination has been on the rise in Afghanistan.It has become a major concern among the policy makers.This paper aims to propose practical options for the management of nitrate contamination in one of Afghanistan’s groundwater polluted provinces,Kabul.The management framework utilized Mann-Kendall and sen slope tests to detect nitrate trend and geostatistical analysis option in Arc GIs 10.5 to assess the nitrate change.To explore the impact of various management options,a number of legislative documents were reviewed.The results indicate a decline in the nitrate storage of Kabul aquifers from 108 mg/L in 2005 to 0.044 mg/L in 2010.Considering the whole period of the study,the results show that the nitrate volumes remain lower than the nitrate concentration range proposed by World Health Organization(50 mg/L).Groundwater dynamics in Kabul aquifers were influenced by nitrate derived from precipitation and nitrate input from root zones in agricultural areas.Finally,different management options for groundwater pollution from nitrate and corresponding authorities,incorporated urban,rural and agriculture,were proposed.It is expected that this study will help policy makers to better manage the nitrate storage of Kabul aquifers by implementing the proposed management options.

We present the behaviors of both dynamical and static charge susceptibilities of doped armchair nanotubes using the Green function approach in the context of Holstein-model Hamiltonian.specially,the effects of magnetization and gap parameter on the the plasmon modes of armchair nanotube are investigated via calculating correlation function of charge density operators.Random phase approximation has been implemented to find the interacting dynamical charge susceptibility.The electrons in this systems interacts with each other by mediation of dispersionless Holstein phonons.Our results show that the increase of gap parameter leads to decreasing intensity of charge collective mode.Also the frequency position of the collective mode tends to higher frequencies due to the gap parameter.Furthermore the number of collective excitation mode decreases with chemical potential in the presence of electron-phonon interaction.Finally the temperature dependence of static charge structure factor of armchair nanotubes is studied.The effects of the gap parameter,magnetization and electron-phonon interaction on the static structure factor are addressed in details.
