Abstract
Saffron, the "golden spice" derived from Crocus sativus L., is renowned for its richness in secondary metabolites such as crocin and safranal, contributing to its unique properties. Facing challenges like decreasing global production, optimizing cultivation techniques becomes imperative for enhanced yields. Although the impact of factors like planting density, planting depth, spacing, and corm size on saffron growth has been studied, the interaction between corm size and planting depth remains underexplored. This study systematically investigates the interactive effects of corm size and planting depth on saffron growth and yield, providing evidence-based guidelines for optimizing cultivation. A factorial experiment, employing a completely randomized design, was conducted to assess the influence of corm size (05-10g, 10.1-15g, 15.1-20g) and planting depth (10cm, 15cm, 20cm) on saffron yield. Uniform-sized corms were obtained, and a suitable soil mixture was prepared for cultivation. Morphological and agronomic parameters were measured, and statistical analyses were performed using ANOVA and Tukey's HSD test. The study revealed that planting depth significantly affected saffron emergence. The corms sown under 15cm depth showed 100% emergence regardless of corm size (either 05-10g, 10.1-15g, 15.1-20g) followed by 10cm depth corms. Corm dry weight exhibited a complex interaction, where larger corms benefited from deeper planting, while intermediate-sized corms thrived at shallower depths. Similar patterns were observed in shoot fresh weight and dry weight. Specifically, the largest corm size (t3, 15.1-20g) produced the greatest fresh-weight biomass at the deepest planting depth of 20cm (T3), while intermediate-sized corms (t2, 10.1-15g) were superior at the shallowest 10cm depth (T1). The total plant biomass demonstrated that larger corms excelled in deeper planting, while intermediate-sized corms were optimal at moderate depths. This research highlights the intricate interplay between corm size and planting depth in influencing saffron growth. Larger corms generally promote higher biomass, but the interaction with planting depth is crucial. Understanding these dynamics can aid farmers in tailoring cultivation practices for optimal saffron yields. The study emphasizes the need for a coordinated approach to corm selection and depth placement, providing valuable insights for sustainable saffron production and economic growth.

Abstract
BACKGROUND Liver disorders are important adverse effects associated with antifungal drug treatment. However, the accuracy of Clinical International Classification of Diseases (ICD)-10 codes in identifying liver disorders for register based research is not well-established. This study aimed to determine the positive predictive value (PPV) of the ICD-10 codes for identifying patients with toxic liver disease, hepatic failure, and jaundice among patients with systemic antifungal treatment. METHODS Data from the Swedish Prescribed Drug Register and the National Patient Register were utilized to identify adult patients who received systemic azole antifungal drugs and had a recorded diagnosis of toxic liver disease (K71.0, K71.1, K71.2, K71.6, K71.8, K71.9), hepatic failure (K72.0, K72.9), or jaundice (R17) between 2005 and 2016. The medical records of all included patients were reviewed. Prespecified criteria were used to re-evaluate and confirm each diagnosis, serving as the gold standard to calculate PPVs with 95% confidence intervals (95% CI) for each diagnostic group. RESULTS Among the 115 included patients, 26 were diagnosed with toxic liver disease, 58 with hepatic failure, and 31 with jaundice. Toxic liver disease was confirmed in 14 out of 26 patients, yielding a PPV of 53.8% (95% CI 33.4-73.4%). Hepatic failure was confirmed in 26 out of 38 patients, resulting in a PPV of 62.1% (95% CI 48.4-74.5%). The highest PPV was found in jaundice, with 30 confirmed diagnoses out of 31, yielding a PPV of 96.8% (95% CI 83.3-99.9%). CONCLUSION Among patients who received azole antifungal treatment and were subsequently diagnosed with a liver disorder, the PPV for the diagnosis of jaundice was high, while the PPVs for toxic liver disease and hepatic failure were lower.

Abstract
Theileria sp. (Piroplasmida: Theileriidae) is one of the most widely known infections transmitted by hard ticks (Acari: Ixodidae) and has been linked to significant economic losses across the globe. The study's main emphasis was theileriosis, a disease that is common in Pakistan and has an incidence ranging from 0.6% to 33%. Through DNA screening of the vector ticks and host blood, this study sought to determine the risk of tick-borne theileriosis in populations of buffalos (Bubalus bubalis) and cattle (Bos indicus) in Toba Tek Singh district of Punjab, Pakistan. Identified tick species include Hyalomma anatolicum (35.4%), Rhipicephalus (Boophilus) microplus (30.2%), and R. sanguineus (25%). Tick specimens were collected from animals and their respective microenvironments. PCR assays targeting Theileria annulata were used to investigate the infection in the DNA extracted from the collected blood samples from large ruminants and salivary glands (SGs) of the Hyalomma ticks. The 18S rRNA of T. annulata was amplified using specific primers. Positive T. annulata amplicons were sequenced and verified using BLAST analysis. Overall, 50% of SGs contained T. annulate DNA. Female ticks, and those collected from cattle and from riverine environments had significantly higher (p < 0.05) rates of Theileria infection in their acini. Overall prevalence of Theileria infection was 35.9% in blood collected from large ruminants. Cattle had a substantially greater frequency of bovine theileriosis (43.2%) than buffalos (28.7%). Age and sex of large ruminants were significantly positively associated (p < 0.05) with Theileria infection. Furthermore, compared to non-riverine cattle (35%) and buffalo (19.5%), riverine cattle (52.2%) and buffalo (36.2%) showed a considerably higher prevalence. The results of this study, which is the first in Pakistan to examine the blood of large ruminants and vectorial function of Ixodid ticks in the transmission of T. annulata along with associated risk factors, offer an important insight for risk assessment of Theileria infection in livestock using vectorial infectivity.

Abstract
We started a campaign in the heart of Faisalabad, Punjab, Pakistan, to expose the hidden threats of parasitic illnesses in ruminants and the severe financial consequences associated with them. Our in-depth investigations focused on the prevalence, impact, and astounding financial losses brought on by organ contamination in slaughtered animals. Of the 384 slaughtered ruminants examined for gastrointestinal parasites, a prevalence of 44.79% was recorded. It is interesting to note that we found no conclusive association between parasitic infection and the various ruminant species under study (p > 0.05). However, goats (52.0%) had the highest numerical prevalence of parasitic infection, followed by cattle (46.1%), buffalo (46.0%), and sheep (34.7%) in that order. A significant finding (p < 0.05) showed that the majority of animals had light parasitism (46.5%), as opposed to those with moderate (30.2%) or severe loads (23.2%). Our research revealed substantial (p < 0.05) relationships between ruminant age, sex, and parasitic infection prevalence. In comparison to females (56.4%) and adults (48.1%), males (36.1%) and young (36.9%) ruminants showed considerably decreased infection rates (p < 0.05). On the other hand, we discovered a non-significant (p > 0.05) association between the months and the prevalence of parasitic infection. As a result of the condemnation of contaminated organs such as the rumen, lungs, and liver, an estimated financial loss of PKR 133,731,400 (USD = 466,939.2) was incurred. The yearly economic losses caused by liver condemnation were much greater than those caused by rumen and lung condemnation (p < 0.05). Our research not only reported a significantly higher abundance but also economic threats of the parasitic diseases among the slaughtered animals in Faisalabad, Punjab, Pakistan. Our findings highlighted the critical need for preventive and therapeutic interventions for parasitic infections in animals, in order to mitigate the economic losses through strengthened animal health.

Abstract
This study was designed to evaluate the trace elements (minerals) in forages fed to sheep and their effect on gastrointestinal parasite burdens. The ultimate objective was to determine the correlation between the burden of gastrointestinal (GI) parasites and the level of trace minerals in sheep serum as a result of the forages they grazed on. A total of 384 faecal samples were collected from sheep in each of the districts (Sialkot and Multan) and examined quantitatively using the McMaster technique. Serum collected from them and plants were pre-treated, and spectrophotometry was used to determine the concentration of trace minerals (Mn, Co, Cu, and Zn). The level of these trace elements differed significantly (P < 0.05) in forages from both districts. In the district of Sialkot, the highest concentrations (mg/Kg) of Zn (38.53 ± 0.16) were found in Cichorium intybus, Cu (41.57 ± 0.07) in Cynodon dactylon, Mn (39.61 ± 0.05) in Parthenium hysterophorus, and Co (1.42 ± 0.03) in Coronopus didymus. In the district of Multan, the highest concentrations (mg/Kg) of Zn (39.43 ± 0.46) were found in Cichorium intybus, Cu (25.76 ± 0.36) in Cynodon dactylon, Mn (34.29 ± 0.53) in Launaea nudicaulis, and Co (1.74 ± 0.08) in Brachiaria raptens. The prevalence of GI parasites in sheep populations in district Sialkot was 34%, while in district Multan, it was 32%. In tehsil Sialkot of district Sialkot, Zn and Cu were significantly (P < 0.05) correlated with eggs per gram (EPG) of faeces, while in tehsil Multan City of district Multan, only Cu was significantly (P < 0.05) correlated with EPG. The potential mechanism behind the role of trace minerals in lowering the burdens of GI parasites requires more investigation. It is recommended that plants with high content of trace minerals should be utilized as part of comprehensive preventive and control strategies against GI parasitism in ruminant animals like sheep.

Abstract
This study was conducted to compare the scrotal skin dynamics of camel and buffalo bulls regarding thermoregulation, season and testosterone. Scrotal skin and blood samples (n = 8 each) were collected during breeding (October to March) and non-breeding seasons (April to August). Tissue slides were prepared by the paraffin embedding technique followed by hematoxylin and eosin (H&E) staining and were analysed by ImageJ®. Relative humidity and temperature were recorded in different seasons to calculate the thermal humidity index (THI). Serum testosterone level was estimated through radioimmunoassay (RIA). The data were analysed by applying ANOVA, the THS test was used as a post-ANOVA interface and the correlation coefficient was also calculated among season, testosterone and skin parameters. The results showed that skin thickness, season and THI were negatively correlated with testosterone levels. In the neck, body and apex, the papillary layer was thicker in buffalo bull compared to camel bull during the breeding season; however, the reticular layer followed a reverse trend in the apex when THI was low. In the scrotal neck during the non-breeding season, hair follicle (HF) length and density were recorded high in camel bull compared to buffalo bull when THI was elevated. The density of HF followed the otherwise trend in the apex during the breeding season. The density of SG was found highest in all regions of camel bull as compared to buffalo bull and showed direct relation with THI. To conclude, this study delineates how the histo-dynamics of scrotal skin varies and accommodate itself with testosterone and THI over the different season in camel and buffalo.

Abstract
As a central part of the mammalian brain, the prefrontal cortex (PFC) has been implicated in regulating cocaine-induced behaviors including compulsive seeking and reinstatement. Although dysfunction of the PFC has been reported in animal and human users with chronic cocaine abuse, less is known about how the PFC is involved in cocaine-induced behaviors. By using two-photon Ca2+ imaging to simultaneously record tens of intact individual networking neurons in the frontal association cortex (FrA) in awake male mice, here we report that a systematic acute cocaine exposure decreased the FrA neural activity in mice, while the chemogenetic intervention blocked the cocaine-induced locomotor sensitization. The hypoactivity of FrA neurons was critically dependent on both dopamine transporters and dopamine transmission in the ventromedial PFC (vmPFC). Both dopamine D1R and D2R neurons in the vmPFC projected to and innervated FrA neurons, the manipulation of which changed the cocaine-induced hypoactivity of the FrA and locomotor sensitization. Together, this work demonstrates acute cocaine-induced hypoactivity of FrA neurons in awake mice, which defines a cortico-cortical projection bridging dopamine transmission and cocaine sensitization.

Abstract
Cystic echinococcosis (hydatidosis) is a world-wide zoonotic disease of mainly humans, livestock and dogs, caused by Echinococcus granulosus. The disease can negatively impact food production and animal welfare and causes socio-economic hardship. Here, we aimed to identify the local bovine hydatid cyst fluid (BHCF) antigen for developing a sero-diagnostic assay to be used for the pre-slaughter screening of food animals. In total, 264 bovines approved for slaughter in Pakistan were subjected to serum collection and post-mortem screening for hydatid cysts. These cysts were assessed microscopically to assess fertility and viability, and by PCR for molecular confirmation of species. A BHCF antigen was identified from positive sera via SDS-PAGE, confirmed by Western blot, and quantified via a bicinchoninic acid (BCA) assay. The quantified crude BHCF antigen (iEg67 kDa) was then used in ELISA screening to test all sera collected from known positive and negative animals based on hydatid cyst presence/absence. Of the 264 bovines examined, 38 (14.4%) showed hydatid cysts during post-mortem examination. All of these individuals, plus an additional 14 (total: 52; 19.6%) tested positive based on less time-consuming ELISA examination. Based on ELISA, occurrence in females (18.8%) was significantly higher than in males (9.2%) and was higher in cattle (19.5%) compared to buffalo (9.5%). The infection rate increased with age in both host species: cumulatively, 3.6% in animals aged 2-3 years, 14.6% in 4-5-year-olds and 25.6% in 6-7-year-olds. The occurrence of cysts in cattle was significantly higher in the lungs (14.1%) compared to their livers (5.5%), whereas the opposite was true in buffalo (6.6% livers, 2.9% lungs). For both host species, most cysts in the lungs were fertile (65%), while the majority in the liver were sterile (71.4%). We conclude that the identified iEg67 kDa antigen is a strong candidate for the development of a sero-diagnostic screening assay for the pre-slaughter diagnosis of hydatidosis.

Abstract
Introduction Intellectual disability (ID) is a lifelong disability that affects an individual‧s learning capacity and adaptive behavior. Such individuals depend on their families for day-to-day survival and pose a significant challenge to the healthcare system, especially in developing countries. ID is a heterogeneous condition, and genetic studies are essential to unravel the underlying cellular pathway for brain development and functioning. Methods Here we studied a female index patient, born to a consanguineous Pakistani couple, showing clinical symptoms of ID, ataxia, hypotonia, developmental delay, seizures, speech abnormality, and aggressive behavior. Whole exome sequencing (WES) coupled with Sanger sequencing was performed for molecular diagnosis. Further, 3D protein modeling was performed to see the effect of variant on protein structure. Results WES identified a novel homozygous missense variant (c.178T>C; p.Tyr60His) in the ANK3 gene. In silico analysis and 3-dimensional (3D) protein modeling supports the deleterious impact of this variant on the encoding protein, which compromises the protein‧s overall structure and function. Conclusion Our finding supports the clinical and genetic diversity of the ANK3 gene as a plausible candidate gene for ID syndrome. Intelligence is a complex polygenic human trait, and understanding molecular and biological pathways involved in learning and memory can solve the complex puzzle of how cognition develops. Intellectual disability (ID) is defined as a deficit in an individual‧s learning and adaptive behavior at an early age of onset [American Psychiatric Association, 2013]. It is one of the major medical, and cognitive disorders with a prevalence of 1-3% in the population worldwide [Leonard and Wen, 2002]. ID often exists with other disabling mental conditions such as autism, attention deficit hyperactivity disorder, epilepsy, schizophrenia, bipolar disorder, or depression. Almost half of the cases appear to have a genetic explanation that ranges from cytogenetically visible abnormalities to monogenic defects [Flint, 2001; Ropers, 2010; Tucker-Drob et al., 2013]. Intellectual disability is a genetically heterogeneous condition, and more than 700 genes have been identified to cause ID alone or as a part of the syndrome. Research in X-linked ID has identified more than 100 disease-causing genes on the X chromosome that play a role in cognition; however, research into autosomal causes of ID is still ongoing [Vissers et al., 2016].

Abstract
Introduction: The area of "Green Synthesis of Nano-medicine," as compared to its synthetic counterparts, is a relatively safer research technology for various biomedical applications, including identification, therapeutic application, and prevention of pathological conditions, pain control, safety, and development of human wellness. The present study explored the synthesis and characterization of AgNPs using the ethanolic extract of Piper cubeba fruit as a reducing and stabilizing agent and its potential as an enzyme inhibitory agent. Urease inhibitors are helpful against many severe diseases, including gastric ulcers induced by Helicobacter pylori. Method: The fruits of the Piper cubeba plant were taken and ground to a fine powder. Plant material was added to 500 ml ethanol, and the mixture was filtered. The solvent of the filtrate was evaporated, and a thick, gummy extract was obtained and stored at 4°C in the refrigerator. AgNPs were green synthesized from solutions of AgNO3 using the P. cubeba extract, which was indicated by a change in the color from light brown to deep brown. The synthesized AgNPs were characterized via Ultraviolet-visible (UV-Vis) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Results and Discussion: Analysis showed the reduction of Ag+ to Ag0 at room temperature (25°C), and the average particle size of AgNPs was in the range of 40-80 nm. Consequently, the synthesized AgNPs were evaluated for their anti-urease activity. The maximum urease inhibition of the Piper cubeba ethanolic extract was 88.5% at 5 mg conc., and of derived nanoparticles was 78.6% at 0.05 mg conc. The results were nearly similar to the control drug, i.e., thiourea (0.5 and 0.6 mM conc., respectively). Conclusion: The study concluded that the P. cubeba extract, as well as its green-derived AgNPs, might prove to be a better and safer substitute for their enzyme inhibitory potential in emerging medicine and novel drug delivery techniques to improve and maintain human health.

Abstract
The present study reports the prevalence of Paramphistomum spp. in small and large ruminants and their association with the histopathology of the infected rumens. A total of 384 animals were screened for Paramphistomum spp. The animals found positive for Paramphistomum spp. were divided into three groups according to the worm load/5 cm2 (G1: 10 - 20 worms/5 cm2 = Low, G2: 20 - 40 worms/5 cm2 = Medium, and G3: >41 worms/5 cm2 = High). Tissue slides were prepared from samples of the rumen (1 cm2) taken from animals positive for ruminal fluke to determine the histological parameters, including epithelial length or thickness, length and width of the ruminal papilla, and thickness of tunica submucosa and mucularis externae. The overall prevalence of Paramphistomum spp. in the ruminant population of district Narowal was 56.25 % with a significant (P < 0.05) variation among different species of ruminants. The highest prevalence was in cattle, followed in order by buffalo, goat, and sheep. Epithelium thickness was significantly correlated with parasite load in large ruminants and the most significant (P < 0.05) decrease in epithelium thickness was in Group B (31.12 ± 1.82 μm) and Group C (31.07 ± 1.68 μm) and a same trend was recorded in small ruminants. Histopathological changes due to Paramphistomum spp. are reported for the first time, which explained the histomorphological and physiological changes in Paramphistomum-infected rumens which might be associated with lowered feed efficiency and productivity in ruminants.

Abstract
Spondylocostal dysostosis is a genetic defect associated with severe rib and vertebrae malformations. In recent years, extensive clinical and molecular diagnosis advancements enabled us to identify disease-causing variants in different genes for such severe conditions. The identification of novel candidate genes enabled us to understand the developmental biology and molecular and cellular mechanisms involved in the etiology of these rare diseases. Here, we discuss the clinical and molecular targets associated with spondylocostal dysostosis, including clinical evaluation, genes, and pathways involved. This review might help us understand the basics of such a severe disorder, which might help in proper clinical characterization and help in future therapeutic strategies.

Abstract
The norepinephrine neurons in locus coeruleus (LC-NE neurons) are essential for sleep arousal, pain sensation, and cocaine addiction. According to previous studies, cocaine increases NE overflow (the profile of extracellular NE level in response to stimulation) by blocking the NE reuptake. NE overflow is determined by NE release via exocytosis and reuptake through NE transporter (NET). However, whether cocaine directly affects vesicular NE release has not been directly tested. By recording quantal NE release from LC-NE neurons, we report that cocaine directly increases the frequency of quantal NE release through regulation of NET and downstream protein kinase C (PKC) signaling, and this facilitation of NE release modulates the activity of LC-NE neurons and cocaine-induced stimulant behavior. Thus, these findings expand the repertoire of mechanisms underlying the effects of cocaine on NE (pro-release and anti-reuptake), demonstrate NET as a release enhancer in LC-NE neurons, and provide potential sites for treatment of cocaine addiction.

Abstract
The purpose of this study was to purify the phytoconstituents and to explore the antibacterial, antifungal, phytotoxic and cytotoxic potential of dichloromethane and methanol extracts of aerial and root parts of Trigonella polycerata. The phytochemical study on methanol extract of aerial parts of the plant led to the isolation and purification of seven compounds that were identified as 3,4-dimethoxycinnamaldehyde, Trigocoumarin, 6,7,8-trimethoxycoumarin, Penduletin, 5-hydroxy-3,6,7,4´-tetramethoxyflavone, 3,5,7-trihydroxy-6,4-dimethoxyflavone and 5-hydroxy-4,7-dimethoxyflavone. These structures were elucidated by interpretation of EI-MS and NMR spectral data. The plant aerial parts methanol extract (TPAM) demonstrated higher antibacterial (78.99%), phytotoxic (85% growth regulation at 1000μg/mL) and cytotoxic activities (LD50: 45.643μg/mL). While the methanol root extract (TPRM) was highly active against bacteria's; Salmonella typhi (71.56%), Staphylococcus aureus (70.15%), Escherichia coli (69%), fungi like Candida albicans (70.21%) and moderately active against Brine shrimp larvae (LD50: 125.663μg/mL). The dichloromethane aerial (TPAD) and root (TPRD) extracts exhibited significant antibacterial (78.03% and 50.21% inhibitions respectively) and phytotoxic (55% growth regulation at 1000μg/mL) potential. Only TPAD indicated the best inhibition against fungi; Aspergillus flavus (75.31%) and moderate inhibition against Microsporum canis (42.21%). This phytochemical and biological work is the first time reported in Trigonella polycerata.

Abstract
Hearing impairment (HI) is a heterogeneous condition that affects many individuals globally with different age groups. HI is a genetically and phenotypically heterogeneous disorder. Over the last several years, many genes/loci causing rare autosomal recessive and dominant forms of hearing impairments have been identified, involved in various aspects of ear development. In the current study, two affected individuals of a consanguineous family exhibiting autosomal recessive nonsyndromic hearing impairment (AR-NSHI) were clinically and genetically characterized. The single affected individual (IV-2) of the family was subjected to whole-exome sequencing (WES) accompanied by traditional Sanger sequencing. Clinical examinations using air conduction audiograms of both the affected individuals showed profound hearing loss across all frequencies. WES revealed a homozygous missense variant (c.44G>C) in the SIX5 gene located on chromosome 19q13.32. We report the first case of autosomal recessive NSHI due to a biallelic missense variant in the SIX5 gene. This report further supports the evidence that the SIX5 variant might cause profound HI and supports its vital role in auditory function. Identification of novel candidate genes might help in application of future gene therapy strategies that may be implemented for NSHI, such as gene replacement using cDNA, gene silencing using RNA interference, and gene editing using the CRISPR/Cas9 system.

Abstract
Background Limited real-world data from routine clinical care are available on the safety and effectiveness of treatment with taliglucerase alfa in patients with Gaucher disease (GD). Methods Taliglucerase Alfa Surveillance (TALIAS), a multinational prospective Drug Registry of patients with GD, was established to evaluate the long-term safety (primary objective) and effectiveness (secondary objective) of taliglucerase alfa. We present an interim analysis of the data from the Drug Registry collected over the 5-year period from September 2013 to January 2019. Results A total of 106 patients with GD (15.1% children aged < 18 years; 53.8% females) treated with taliglucerase alfa have been enrolled in the Drug Registry, as of January 7, 2019. The median duration of follow-up was 795 days with quartiles (Q1, Q3) of 567 and 994 days. Fifty-three patients (50.0%) were from Israel, 28 (26.4%) were from the United States, and 25 (23.6%) were from Albania. At the time of enrollment, most patients (87.7%) had received prior enzyme replacement therapy (ERT). Thirty-nine of the 106 patients had treatment-emergent adverse events (AEs). Twelve of the 106 patients experienced serious AEs; two patients experienced four treatment-related serious AEs. Four patients died, although none of the deaths was considered to be related to taliglucerase alfa treatment by the treating physicians. Nine patients discontinued from the study, including the four who died. At baseline, patients with prior ERT had a higher mean hemoglobin concentration and platelet counts than treatment-naïve patients, likely reflecting the therapeutic effects of prior treatments. During follow-up, the hemoglobin concentration and platelet counts increased in the treatment-naïve patients and remained relatively constant or increased slightly in patients with prior ERT. Spleen and liver volumes decreased in treatment-naïve patients. Conclusions The interim data showed no new or emergent safety signals. The overall interim data are consistent with the clinical program experience and known safety and effectiveness profile of taliglucerase alfa.

Abstract
Euphorbia nivulia-Ham (EN) is a neglected medicinal plant traditionally used for a number of pathologies, but it has not been explored scientifically. In the current study, its various fractions were assessed for their phenolic and flavonoid content, radical scavenging, as well as its enzyme inhibitory potential. The hydro-alcoholic crude extract (ENCr) was subjected to a fractionation scheme to obtain different fractions, namely n-hexane (ENHF), chloroform (ENCF), n-butanol (ENBF), and aqueous fraction (ENAF). The obtained results revealed that the highest phenolic and flavonoid content, maximum radical scavenging potential (91 ± 0.55%), urease inhibition (54.36 ± 1.47%), and α-glucosidase inhibition (97.84 ± 1.87%) were exhibited by ENCr, while the ENBF fraction exhibited the highest acetylcholinestrase inhibition (57.32 ± 0.43%). Contrary to these, hydro-alcoholic crude as well as the other fractions showed no significant butyrylcholinestrases (BChE) and carbonic anhydrase inhibition activity. Conclusively, it was found that EN possesses a significant radical scavenging and enzyme inhibitory potential. Thus, the study may be regarded a step forward towards evidence-based phyto-medicine.

Abstract
BACKGROUND Limb-girdle muscular dystrophy (LGMD) is a heterogeneous group of diseases, which affects different muscles, predominantly skeletal muscles and cardiac muscles of the body. LGMD is classified into two main sub-types A and B, which are further sub-classified into eight dominant and thirty recessive sub-types. Three genes, mainly POPDC1, POPDC2 and POPDC3, encodes popeye domain-containing protein (POPDC), and the variants of POPDC1 and POPDC3 genes have been associated with LGMD. METHODS In this study, we performed whole-exome sequencing (WES) analysis on a single-family to investigate the hallmark features of LGMD. The results of WES were further confirmed by Sanger sequencing and 3D protein modeling was also performed. RESULTS WES data analysis and sanger sequencing revealed a homozygous missense variant (c.460A>G; p.Lys154Glu) at a highly conserved amino acid position in the POPDC3. Mutations in the POPDC3 gene have been previously associated with recessive limb-girdle muscular dystrophy type 26. 3D protein modeling further suggested that the identified variant might affect the POPDC3 structure and proper function. DISCUSSION/CONCLUSIONS This study confirms the role of POPDC3 in LGMD, and will facilitate in genetic counseling of the family to mitigate the risks of the carrier or affected in future pregnancies.

Abstract
Sarcoglycanopathies include four subtypes of autosomal recessive limb-girdle muscular dystrophies (LGMDR3, LGMDR4, LGMDR5 and LGMDR6) that are caused, respectively, by mutations in the SGCA, SGCB, SGCG and SGCD genes. Delta-sarcoglycanopathy (LGMDR6) is the least frequent and is considered an ultra-rare disease. Our aim was to characterize the clinical and genetic spectrum of a large international cohort of LGMDR6 patients and to investigate whether or not genetic or protein expression data could predict diseasés severity. This is a retrospective study collecting demographic, genetic, clinical and histological data of patients with genetically confirmed LGMDR6 including protein expression data from muscle biopsies. We contacted 128 pediatric and adult neuromuscular units around the world that reviewed genetic data of patients with a clinical diagnosis of a neuromuscular disorder. We identified 30 patients with a confirmed diagnosis of LGMDR6 of which 23 patients were included in this study. Eighty seven percent of the patients had consanguineous parents. Ninety one percent of the patients were symptomatic at the time of the analysis. Proximal muscle weakness of the upper and lower limbs was the most common presenting symptom. Distal muscle weakness was observed early over the course of the disease in 56.5% of the patients. Cardiac involvement was reported in 5 patients (21.7%) and 4 patients (17.4%) required non-invasive ventilation. Sixty percent of patients were wheelchair-bound since early teens (median age of 12.0 years old). Patients with absent expression of the sarcoglycan complex on muscle biopsy had a significant earlier onset of symptoms and an earlier age of loss of ambulation compared to patients with residual protein expression. This study confirmed that delta-sarcoglycanopathy is an ultra-rare neuromuscular condition and described the clinical and molecular characteristics of the largest yet-reported collected cohort of patients. Our results showed that this is a very severe and quickly progressive disease characterized by generalized muscle weakness affecting predominantly proximal and distal muscles of the limbs. Similar to other forms of sarcoglycanopathies, the severity and rate of progressive weakness correlates inversely with the abundance of protein on muscle biopsy.

Abstract
Sesuvium sesuvioides (Fenzl) Verdc is traditionally used in the treatment of inflammatory diseases such as arthritis and gout The aim of present study was to assess the possible anti-inflammatory, analgesic and antipyretic potential of the methanol extract of Sesuvium sesuvioides (SsCr) to prove scientifically its folklore use in the inflammatory diseases and to screen its total antioxidant capacity by multiple methods and phytocompounds by GC-MS. The preliminary phytochemical studies showed the presence of phenols, flavonoids, glycosides, coumarin, terpenoids, saponins, fats and carbohydrates in crude extract. The total phenolic contents (27.31 ± 0.28 mg GAE/g) and total flavonoids (3.58 ± 0.12 mgRE/g) values were observed. The antioxidant capacity of SsCr showed significant DPPH, ABTS, CUPRAC, FRAP, PBD and metal chelating results. GC-MS analysis displayed the phytoconstituents with anti-inflammatory potentials such as 2-methoxy-4-vinylphenol, vanillin, umbelliferone, methyl ferulate, palmitoleic acid, methyl palmitate and phytol. SsCr presented noteworthy HRBC membrane stability with maximum inhibition of cell hemolysis (47.79%). In carrageenan-induced hind paw edema assay result showed dose-dependent anti-inflammatory action. SsCr presented significant (p < 0.05) analgesic activity in hot-plate and tail flicking tests similarly it also showed the noteworthy inhibition in pain latency against formalin induced analgesia at 1st and 2nd phases. SsCr reduced the acetic acid-induced writhes at different doses (250, 500 and 750 mg). Results of antipyretic activity of SsCr extract were significant at 500 and 750 mg. The results of in vitro and in vivo experimental studies verified the anti-inflammatory, analgesic and antipyretic potential of Sesuvium sesuvioides and supported the folklore uses of this plant.

Abstract
Echinops echinatus Linn. (Fam. Asteraceae) possesses medicinal value a good deal. The plant is a nerve tonic that stimulates liver and increases appetite, and is effective as anti-inflammatory and in jaundice. Objective of the current study was to standardize Echinops echinatus (E. echinatus), both macroscopically and microscopically. Pharmacognostic standardization with the help of different physicochemical parameters and fluorescence analysis was performed according to the WHO guidelines. Qualitative phytochemical analysis of crude methanolic extract (EME) and various fractions was done. TLC and column chromatographic techniques were employed for presence of various phytoconstituents. Five compounds were isolated from EME using column chromatography, which were characterized by techniques like FTIR and UV. The isolated purified compounds showed different hRf values ranging from 67 to 94. Results of this study may serve as biochemical markers for this medicinally important plant in the pharma industry and plant systematic studies. The current work will help in identification of the species pharmacognostically and anatomically; and phytochemical analysis may help in screening of active constituents responsible for the activity. The study will serve as a reference for correct identification and in checking any type of adulteration. This may also help in differentiating this species from closely related species of the same genus and family.

Abstract
Euphorbia nivulia (EN) one of the members of Euphorbiaceae family, is a medicinal plant of Cholistan Desert (Punjab, Pakistan) that is traditionally used for a number of diseases. The plant is enriched with many phyto-constituents including flavonoids, triterpenes and polyphenols. In present study, crude extract as well as various fractions were assessed for phytochemical analysis, HPLC profiling, radical scavenging property and total phenolic and flavonoid contents. Hydro-alcoholic (70%) crude extract of EN was subjected to fractionation using different solvents including n-hexane, chloroform, butanol and aqueous. After performing the phytochemical screening and HPLC profiling, antioxidant activity was estimated by using DPPH and FRAP assays. Total flavonoid and phenolic contents were also estimated. HPLC analysis confirmed the presence of flavonoids and polyphenols like quercitin, gallic acid, caffeic acid, vanillic acid, benzoic acid, chlorogenic acid, syringic acid and ferulic acid in crude extract as well as butanol and aqueous fractions. Results revealed that butanol fraction showed maximum phenolic (143.26±2.65 mg/g GA/g) and crude extract showed maximum flavonoid (69.80±1.212 mg/g Q) contents. Maximum antioxidant potential was displaced by butanol fraction which was IC50=0.04±0.02 by DPPH and 1193.77±12.4 μmol TE/ml by FRAP respectively. Current study is the first information about the HPLC profiling of phenolic compounds in EN and its antioxidant potential that could be a step forward towards ethno-pharmacological based phyto-medicine.

Abstract
Many phytochemicals can affect the growth and development of plants and insects which can be used as biological control agents. In this study, different concentrations of crude, hexane, chloroform, butanol, and aqueous extracts of Euphorbia nivulia Buch.-Ham., an endemic plant of the Cholistan desert in South Punjab of Pakistan, were analysed for their chemical constituents. Their various concentrations were also tested for their phytotoxic and insecticidal potential against duckweed, Lemna minor L., and the dusky cotton bug, Oxycarenus hyalinipennis Costa. various polyphenols, i.e., quercetin, gallic acid, caffeic acid, syringic acid, coumaric acid, ferulic acid, and cinnamic acid were detected in different concentrations with different solvents during the phytochemical screening of E. nivulia. In the phytotoxicity test, except for 100 μg/mL of the butanol extract gave 4.5% growth regulation, no phytotoxic lethality could be found at 10 and 100 μg/mL of all the extracts. The highest concentration, 1000 μg/mL, of the chloroform, crude, and butanol extracts showed 100, 63.1, and 27.1% of growth inhibition in duckweed, respectively. In the insecticidal bioassay, the highest O. hyalinipennis mortalities (87 and 75%) were recorded at 15% concentration of the chloroform and butanol extracts of E. nivulia. In contrast, the lower concentrations of the E. nivulia extracts caused the lower mortalities. Altogether, these findings revealed that E. nivulia chloroform extracts showed significant phytotoxicity while all the extracts showed insecticidal potential. This potential can be, further, refined to be developed for bio-control agents.

Abstract
Palladium on the polymeric materials (Pd@polymer) as a catalyst is now very promising due to its great prospect for catalytic application. Such material in the form of composites is found to be stable and can be applied as catalyst in organic synthesis like Sonogashira coupling reaction. In the present work, Pd containing conjugated poly-ynes composites (Poly (1,4-bis(dodecyloxy)-2,5-diethynylbenzene) (Poly-DEB)/Pd) were synthesized by varying the addition of Pd in the range of equivalent weight of 8:4, 8:2 and 8:1, maintaining the fixed amount of 1,4-bis(dodecyloxy)-2,5-diethynylbenzene (DEB) through chemical oxidative polymerization technique. Both FTIR and UV-visible spectroscopy confirmed the interactions between DEB and Pd in the composites. The DSC data revealed the improved melting temperature as well as the crystallinity of the composites than the DEB. The PL spectra showed its florescence property. The catalytic capability of the Poly-DEB/Pd composites were examined using the Sonogashira coupling reactions, which demonstrated good yields. The suggested synthetic protocol is very facile, reproducible and beneficial for the fabrication of diverse mono and bimetallic composites with conjugated polymers. The present study also demonstrates the new example of Poly-DEB/Pd composites catalyzed Sonogashira coupling reaction. These composites have a possibility to develop as a commercial reagent in various organic synthesis subjects to its application prospects.

Abstract
Background: Euphorbia nivulia Buch.-Ham (En) is one of the members of Euphorbiaceae family that is rich in phytochemicals including flavonoids, triterpenes and polyphenolics.
Purpose: To evaluate hepato-nephronprotective potential of Euphorbia nivulia.
Study Design: Sprague Dawley rats were used as animal models in the study.
Methods: En hydro alcoholic extract was standardized and managed in high dose (300 mgkg−1 body weight (BW) and low dose (150 mgkg−1 BW) to Sprague Dawley rats, administered with CCl4 (1mlkg−1BW). Silymarin (50 mgkg−1 BW) was taken as positive control. The treatments were given thrice a week. Consequently, blood and hepatic homogenates were collected after 4 weeks of treatment. While the situation of kidney was explored through measurement of serum creatinine, serum urea, sodium and albumin levels. Hepatic and renal samples of rats treated with both 150 and 300 mg/kg of the extract were used for tissue pathological study.
Results: En extract revealed dose dependent moderate level of shelter against CCl4 intoxicated hepato-nephrotoxicity as directed from the acquired results. The decrease of the albumin levels by the maximum dose of the extract exceeded similar to that attained with Silymarin, and the protecting effects of the extract against oxidative destruction were evaluated. Examination of serum show significant (p < 0.05) elevation in the level of aspartate transaminase(AST), alkaline phosphatase(ALP), alanine transaminase(ALT), whereas decline were noted for albumin in CCl4 treated rats. Histopathological cuts and damages were seen in hepatic cells and kidney of rats managed by CCl4. But, co-administration of En extract, dose dependently, improved the CCl4-carried hepatic harms in these limits.
Conclusion: These effects propose that the phyto-ingredients of En extract with known polyphenols were able to improve the oxidative stress brought along with CCl4 and may be a useful healing mediator to manage oxidative stress related disorders like hepato-nephro toxicity.

Abstract
There is a long history of natural products for the treatment of infections and diseases. The objective of present study was to investigate the organoleptic, microscopic, physico-chemical, phytochemical, antidiarrheal and antidiabetic potential of leaf, flowering bud and stem bark of Moringa oleifera L. Macroscopic, microscopic, physico-chemical parameters and phytochemical screening were carried out. Diarrhea was induced with castor oil (10ml/kg), verapamil (3, 10 and 30mg/kg) were used as standard antidiarrheal drug and extract of Moringa oleifera at (100, 300 and 1000mg/kg) was used for treatment. Alpha glucosidase inhibitory assay was carried out by using acarbose (0.5mM) and extracts (5.0 mg/Ml). Diabetes was induced by alloxan (150mg/kg), while glibenclamide (10mg/kg) was used as standard drug, and extracts (at the doses of 500mg/kg) were used to determine the antidiabetic activity. Results showed the presence of primary and secondary metabolites, treatment at the dose of 1.0g/kg of leaf, flowering bud and stem bark showed 94 ±2.527, 85.42±5.460 and 84.58±6.138% protection respectively whereas verapamil (10mg/kg) showed 94.84±3.27% protection. Alpha glucosidase inhibition of stem bark (0.5mg/ml) was 95.43±1.47 and flowering bud 94.78±1.25 whereas acarbose (5mM) inhibition was 92.23±0.14%. Stem bark and flowering bud extract (500mg/kg) decreases the blood glucose level from 388.5±35.83 to 226.3±47.10 and 322.5±48.35 to 173.8±29.5 respectively whereas glibenclamide (10 mg/kg) decreases the blood glucose level from 320.7±22.9 to 146.3±17.7 and increases the body weight of the experimental animal. It was concluded from the results that stem bark has strong antidiabetic potential while leaves of the plant have promising antidiarrheal effect.

Abstract
As an analytic tool in medicine, deep learning has gained great attention and opened new ways for disease diagnosis. Recent studies validate the effectiveness of deep learning algorithms for binary classification of skin lesions (i.e., melanomas and nevi classes) with dermoscopic images. Nonetheless, those binary classification methods cannot be applied to the general clinical situation of skin cancer screening in which multi-class classification must be taken into account. The main objective of this research is to develop, implement, and calibrate an advanced deep learning model in the context of automated multi-class classification of skin lesions. The proposed Deep Convolutional Neural Network (DCNN) model is carefully designed with several layers, and multiple filter sizes, but fewer filters and parameters to improve efficacy and performance. Dermoscopic images are acquired from the International Skin Imaging Collaboration databases (ISIC-17, ISIC-18, and ISIC-19) for experiments. The experimental results of the proposed DCNN approach are presented in terms of precision, sensitivity, specificity, and other metrics. Specifically, it attains 94 % precision, 93 % sensitivity, and 91 % specificity in ISIC-17. It is demonstrated by the experimental results that this proposed DCNN approach outperforms state-of-the-art algorithms, exhibiting 0.964 area under the receiver operating characteristics (AUROC) in ISIC-17 for the classification of skin lesions and can be used to assist dermatologists in classifying skin lesions. As a result, this proposed approach provides a novel and feasible way for automating and expediting the skin lesion classification task as well as saving effort, time, and human life.

Abstract
Bovine brucellosis is a global zoonosis of public health importance. It is an endemic disease in many developing countries including Pakistan. This study aimed to estimate the seroprevalence and molecular detection of bovine brucellosis and to assess the association of potential risk factors with test results. A total of 176 milk and 402 serum samples were collected from cattle and buffaloes in three districts of upper Punjab, Pakistan. Milk samples were investigated using milk ring test (MRT), while sera were tested by Rose–Bengal plate agglutination test (RBPT) and indirect enzyme-linked immunosorbent assay (i-ELISA). Real-time PCR was used for detection of Brucella DNA in investigated samples. Anti-Brucella antibodies were detected in 37 (21.02%) bovine milk samples using MRT and in 66 (16.4%) and 71 (17.7%) bovine sera using RBPT and i-ELISA, respectively. Real-time PCR detected Brucella DNA in 31 (7.71%) from a total of 402 bovine sera and identified as Brucella abortus. Seroprevalence and molecular identification of bovine brucellosis varied in some regions in Pakistan. With the use of machine learning, the association of test results with risk factors including age, animal species/type, herd size, history of abortion, pregnancy status, lactation status, and geographical location was analyzed. Machine learning confirmed a real observation that lactation status was found to be the highest significant factor, while abortion, age, and pregnancy came second in terms of significance. To the authors' best knowledge, this is the first time to use machine learning to assess brucellosis in Pakistan; this is a model that can be applied for other developing countries in the future. The development of control strategies for bovine brucellosis through the implementation of uninterrupted surveillance and interactive extension programs in Pakistan is highly recommended.

Abstract
Tuberculosis is a devastating disease causing high mortality all over the world, especially in the developing countries. Mycobacterium tuberculosis (M. tb) is the causative agent of tuberculosis which replicates in the intracellular environment of host macrophages. Although the host immune system is capable of completely eliminating the pathogen, co-evolution of M. tb with humans has resulted in its ability to hijack the host innate and adaptive immune systems in numerous ways. Limited recent progress has been made in the understanding of M. tb immune escape mechanisms, hence exploration of survival strategies of M. tb has been critically reviewed with an insight into understanding its pathogenesis. We summarized the recent studies regarding the modulation of innate immune response, adaptive immune response, epigenetics and the role of miRNA. All of these advancements suggest that M. tb is well-familiarize with the host immune system and possess the ability to hijack it for intracellular survival.

Abstract
Euphorbia nivulia a locally occurring plant species possesses antiseptic, analgesic and anti-inflammatory properties and is ethnopharmacologically used in various ailments like skin, ear disorders, boils, and worm infestation. Preliminary phytochemical screening showed presence of flavonoids, polyphenolics, glycosides, alkaloids, tannins and triterpenoids in (70% aqueous-ethanolic) Euphorbia nivulia crude extract (En cr) and its four fractions, i.e., hexane fraction (En hex), butanol fraction (En bt), chloroform fraction (En ch), and aqueous fraction (En aq). In current study, Agar well diffusion and time-kill kinetic assays were performed for antimicrobial activity. 300 mg/ml concentration showed maximum inhibitory zone. Highest zone of inhibition (15.5mm) was demonstrated by En ch fraction against Proteus mirabilis. Staphyllococcus aureus was the most sensitive bacteria against whom all fractions except En aq fraction were active. Maximum MIC (15.3 mg/ml) was shown by En ch fraction against Proteus mirabilis. Similarly, En ch fraction showed (15.1 mg/ml) remarkable MIC against Candida albicans. Significant higher antibacterial and antifungal activity was revealed in high concentration. Time-kill kinetics studies revealed bacteriostatic action. Noteworthy antimicrobial activity may be due to bioactive compounds of extract which may be a potential antibacterial and antifungal agent.

Abstract
In this study, we aimed to investigate the antidiabetic effects of Euphorbia nivulia (En), native to Cholistan Desert area of Bahawalpur, Pakistan. First, we performed high-performance liquid chromatography analysis and found that this plant contains ferulic acid, gallic acid, quercetin, benzoic acid, polyphenols, and flavonoids. Then, we performed in vitro and in vivo studies to assess its effects on diabetic Wistar rat model. The experiments were performed and compared with control drug glibenclamide. The 70% hydroalcoholic extract of En exhibited 97.8% in vitro α-glucosidase inhibitory effect at a dose of 1.0 mg/mL. We orally administered the extract of En and control drug to the streptozotocin (STZ)-induced diabetic rats and analyzed its antidiabetic effects. We found that the extract of En with a dose of 500 mg/kg/body weight exhibited significant effect to reduce blood glucose in STZ-induced rats as compared with the control group (P < .001). Our histological data also showed that the extract significantly improved the histopathology of pancreas. Collectively, both in vitro and in vivo studies revealed that En possesses α-glucosidase inhibitory, antioxidant, and anti-hyperglycemic effect in STZ-induced diabetic rats.

Abstract
The loss-of-function mutation in PARK7/DJ-1 is one of the most common causes of autosomal recessive Parkinson's disease, and patients carrying PARK7 mutations often exhibit both a progressive movement disorder and emotional impairment, such as anxiety. However, the causes of the emotional symptom accompanying PARK7-associated and other forms of Parkinson's disease remain largely unexplored. Using two-photon microscopic Ca2+ imaging in awake PARK7-/- and PARK7+/+ mice, we found that (i) PARK7-/- neurons in the frontal association cortex showed substantially higher circuit activity recorded as spontaneous somatic Ca2+ signals; (ii) both basal and evoked dopamine release remained intact, as determined by both electrochemical dopamine recordings and high performance liquid chromatography in vivo; (iii) D2 receptor expression was significantly decreased in postsynaptic frontal association cortical neurons, and the hyper-neuronal activity were rescued by D2 receptor intervention using either local pharmacology or viral D2 receptor over-expression; and (iv) PARK7-/- mice showed anxiety-like behaviours that were rescued by either local D2 receptor pharmacology or overexpression. Thus, for first time, we demonstrated a robust D2 receptor-dependent phenotype of individual neurons within the prefrontal cortex circuit in awake parkinsonian mice that linked with anxiety. Our work sheds light on early-onset phenotypes and the mechanisms underlying Parkinson's disease by imaging brain circuits in an awake mouse model.

Abstract
BACKGROUND Voriconazole is an extended-spectrum antifungal agent approved for the treatment and prophylaxis of invasive aspergillosis and other serious fungal infections. In 2014, additional risk minimization measures (aRMM) consisting of a Healthcare Professional (HCP) Question and Answer (Q&A) Brochure, HCP Checklist, and Patient Alert Card were implemented on a rolling basis across the European Union (EU) to mitigate three key risks with voriconazole: phototoxicity, squamous cell carcinoma (SCC) of the skin, and hepatotoxicity. The risks of phototoxicity and hepatotoxicity have been documented in the Summary of Product Characteristics (SmPC) since voriconazole was first approved in the EU in 2002. However, the risk of SCC of the skin was a more recent addition to the SmPC (added in 2010). OBJECTIVES We evaluated the effectiveness of the aRMM, as per EU Good Pharmacovigilance Practices Module XVI, via a survey of HCPs. METHODS An online survey was conducted among specialty care HCPs in 10 EU countries who had received by mail aRMM tools 12 months previously. Survey questions evaluated HCPs' receipt and utilization of aRMM tools, and knowledge of the three risks. RESULTS Of 27,396 HCPs invited to participate, 332 eligible respondents completed the survey (response rate: 447/26,735; 1.7%). In total, 19.6% of respondents recalled receiving the HCP Q&A Brochure, 22.6% the HCP Checklist, and 25.9% the Patient Alert Card. HCPs had a high level of knowledge of phototoxicity and hepatotoxicity; however, knowledge of SCC was lower. Knowledge of the three risks and self-reported risk minimization behavior was slightly improved in those who had read the HCP Q&A Brochure compared with those who had not. CONCLUSION The effectiveness of the voriconazole aRMM cannot be meaningfully inferred from the results due to the low survey response rate. The assessment indirectly points to the SmPC or other resources being the main source of risk information for HCPs. Engaging HCPs before designing and implementing an aRMM program is crucial to ensure an effective and focused program. (EU PAS registration number: EUPAS12624).

Abstract
Abstract
Direct evidence of the control of yield, thermal stability and photoluminescence property of the polyaniline (PANI) nanofibers have been reported by systematically varying the reaction time in the range of 2–6 hours (h) in the synthesis process. Both FTIR and UV–visible spectra revealed the formation of PANI fibers for all synthesis batches. The mass of the obtained PANI was increased with the increase of reaction time from 2 to 6 h. FESEM data confirmed the formation of PANI in nanofibers form for all the synthesis batches. TGA data showed that the highest thermal stability of PANI nanofibers could be obtained for the 4 h reaction time. PL data indeed showed the variation of luminescence intensity of PANI with the reaction time which indicate the formation of different quality fibers in terms of their π conjugation. Thus the three main results can be summarized: one is the increase of PANI fibers yield and another two are the thermal stability and luminescence property modification which shows that such properties of PANI can be controlled by varying the reaction time of the synthesis process.

Abstract
Striatal dopamine (DA) release plays an essential role in many physiological functions including motor and non-motor behaviors (such as reward, motivation, and cognition). We have previously reported that, following a single electrical field stimulation, the amperometric recording of DA release from presynaptic terminals in striatal slices (both ventral and dorsal) contains two temporally separated phases. The first phase (direct DA transmission, direct DT) arises from DA terminal release following autologous action potentials (APs), while the second phase (cholinergic transmission-induced DA transmission, CTDT) arises from delayed DA release triggered by the activation of cholinergic interneurons to DA terminals (axon-axon transmission). The millisecond time-resolution of amperometry permits separation of an ∼7 ms latency difference from the single synapse (axon-axon) within the two-phase DA-release (2pDA) signal, and thus the 2pDA signal provides a novel method to study either direct DT, or CTDT, or both. Here, we describe the 2pDA method, including signal recording, processing, analysis, and troubleshooting (anti-artifact). Compared with other DA assays using different stimuli, recording methods, and preparations (such as high performance liquid chromatography or fast scan cyclic voltammetry), 2pDA recording is a novel and powerful physiological recording method for the study of DA transmissions in situ.

Abstract
Human population has been increasing rapidly, which ultimately increases human consumption, especially, animal protein requirements. Therefore, demands of animal protein consumption are increasing worldwide at an extraordinary rate. In order to meet the protein demand, intensive animal and aquaculture farming are considered. Like livestock farming (poultry, pigs, sheep, livestock, horses, rabbits, etc.), aquaculture farming (fish, crustaceans, mollusks, etc.) is also becoming the globe's emergent protein production sector. More than 580 aquaculture species are farmed worldwide. Current food animal and aquaculture farming are coupled with standard usage of antimicrobials. The antimicrobial drugs are major solutions for the management of contagious illnesses in food animals and aquaculture. In animal husbandry, antimicrobials are widely utilized for animal therapy, prophylaxis, or as growth promoters. Imprudent usage of these antimicrobials in food animals and aquaculture is a major contributing factor in the spread of antimicrobial resistance. The widespread use of veterinary medicines is considered to signify a frightening population health threat. It not only results in the disclosure and escalation of resistant microbes but also causes other individual, animal, and ecological deterioration. The contribution of resistant microbes from various sources seems to be the major base of resistance in the environment. However, strict policies and regulations for antimicrobial usage in food animals and aquaculture must be made and applied. It is important to prevent their negative effects in humans, food animals, aquaculture, and the environment.

Abstract
The rapid increase in urbanization has given rise to the need of proper waste management. Within municipal waste, the plastic waste is a growing concern which is causing severe harm to our ecosystem. If ignored, this problem will have harmful effects on both human and wildlife. Therefore, this study aims to find out the factors that influence the recycling behavior patterns of consumers regarding plastic waste. The variables from the theory of planned behavior were adopted to study the behavior of consumers toward recycling plastic waste. The data was collected from 243 residents of Karachi-metropolitan city of Pakistan. The partial least square-structural equation modelling was applied to analyze the data. The findings of the current study reveal that different consumers' attributes and attitudes trigger different types of recycling behavior when it comes to waste disposal. Pressure from family and friends and perceived behavioral control trigger the behavior of reselling the waste plastic products while consumer's awareness of consequences and personal attitude toward proper waste disposal leads to reuse or donating that product to someone who can use that plastic product. The understanding of these consumer attributes may help to shape the behavioral outcomes in order to manage waste disposal. This study will be beneficial for business managers looking to improve reverse logistics as well as government/municipal policy makers and academics/researchers who are interested in a solution-oriented study.
