The recent pandemic of coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 has raised global health concerns. The viral 3-chymotrypsin-like cysteine protease (3CLpro) enzyme controls coronavirus replication and is essential for its life cycle. 3CLpro is a proven drug discovery target in the case of severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). Recent studies revealed that the genome sequence of SARS-CoV-2 is very similar to that of SARS-CoV. Therefore, herein, we analysed the 3CLpro sequence, constructed its 3D homology model, and screened it against a medicinal plant library containing 32,297 potential anti-viral phytochemicals/traditional Chinese medicinal compounds. Our analyses revealed that the top nine hits might serve as potential anti- SARS-CoV-2 lead molecules for further optimisation and drug development process to combat COVID-19.

BACKGROUND:
Pilea umbrosa (Urticaceae) is used by local communities (district Abbotabad) for liver disorders, as anticancer, in rheumatism and in skin disorders.
METHODS:
Methanol extract of P. umbrosa (PUM) was investigated for the presence of polyphenolic constituents by HPLC-DAD analysis. PUM (150 mg/kg and 300 mg/kg) was administered on alternate days for eight weeks in rats exposed with carbon tetrachloride (CCl). Serum analysis was performed for liver function tests while in liver tissues level of antioxidant enzymes and biochemical markers were also studied. In addition, semi quantitative estimation of antioxidant genes, endoplasmic reticulum (ER) induced stress markers, pro-inflammatory cytokines and fibrosis related genes were carried out on liver tissues by RT-PCR analysis. Liver tissues were also studied for histopathological injuries.
RESULTS:
Level of antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) and glutathione (GSH) decreased (p < 0.05) whereas level of thiobarbituric acid reactive substance (TBARS), HO and nitrite increased in liver tissues of CCl treated rat. Likewise increase in the level of serum markers; alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and total bilirubin was observed. Moreover, CCl caused many fold increase in expression of ER stress markers; glucose regulated protein (GRP-78), x-box binding protein1-total (XBP-1 t), x-box binding protein1-unspliced (XBP-1 u) and x-box binding protein1-spliced (XBP-1 s). The level of inflammatory mediators such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1) was aggregated whereas suppressed the level of antioxidant enzymes; γ-glutamylcysteine ligase (GCLC), protein disulfide isomerase (PDI) and nuclear erythroid 2 p45-related factor 2 (Nrf-2). Additionally, level of fibrosis markers; transforming growth factor-β (TGF-β), Smad-3 and collagen type 1 (Col1-α) increased with CCl induced liver toxicity. Histopathological scrutiny depicted damaged liver cells, neutrophils infiltration and dilated sinusoids in CCl intoxicated rats. PUM was enriched with rutin, catechin, caffeic acid and apigenin as evidenced by HPLC analysis. Simultaneous administration of PUM and CCl in rats retrieved the normal expression of these markers and prevented hepatic injuries.
CONCLUSION
Collectively these results suggest that PUM constituted of strong antioxidant chemicals and could be a potential therapeutic agent for stress related liver disorders.

The papain-like protease (PLpro) is vital for the replication of coronaviruses (CoVs), as well as for escaping innate-immune responses of the host. Hence, it has emerged as an attractive antiviral drug-target. In this study, computational approaches were employed, mainly the structure-based virtual screening coupled with all-atom molecular dynamics (MD) simulations to computationally identify specific inhibitors of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) PLpro, which can be further developed as potential pan-PLpro based broad-spectrum antiviral drugs. The sequence, structure, and functional con-serveness of most deadly human CoVs PLpro were explored, and it was revealed that functionally important catalytic triad residues are well conserved among SARS-CoV, SARS-CoV-2, and middle east respiratory syndrome coronavirus (MERS-CoV). The subsequent screening of a focused protease in-hibitors database composed of ~7,000 compounds resulted in the identification of three candidate compounds, ADM_13083841, LMG_15521745, and SYN_15517940. These three compounds established conserved interactions which were further explored through MD simulations, free energy calculations, and residual energy contribution estimated by MM-PB(GB)SA method. All these compounds showed stable conformation and interacted well with the active residues of SARS-CoV-2 PLpro, and showed consistent interaction profile with SARS-CoV PLpro and MERS-CoV PLpro as well. Conclusively, the re-ported SARS-CoV-2 PLpro specific compounds could serve as seeds for developing potent pan-PLpro based broad-spectrum antiviral drugs against deadly human coronaviruses. Moreover, the presented infor-mation related to binding site residual energy contribution could lead to further optimization of these compounds.

Purpose::To investigate the orthopedic injuries sustained while driving and using social media on cellular phones from an orthopedic resident's perspective.Methods::A total of 118 patients who presented with a history of road traffic accident secondary to social media usage and suffered from fractures were included in this cross-sectional study. These patients were reported from October 2018 to April 2019. We collected the data including the type of collision, type of social media usage during driving, location of injury, wearing of safety equipment's such as helmet and seat belt during driving.Results::The mean age of patients was (34.86 ± 12.73) (range 15-71) years. The common types of accident on the basis of collision of vehicles were: car versus motorbike 45 (38.1%), motorbike versus motorbike 28 (23.7%), and motorbike versus pedestrian 22 (18.6%). Most of the accidents (61, 51.7%) occurred due to mistake of motor-bikers. Out of them, 44 (37.3%) occurred on traffic signals, followed by 29 (24.6%) while driving on main roads. The common timing of accident was normal hours with frequency of 44 (37.3%), followed by 39 (33.1%) at late night. According to fracture type, closed injuries were 98 (83.1%) and open fractures were 20 (16.9%). The most common fracture was clavicular fracture (21, 22.5%) followed by soft tissue injury in 19 (16.1%) patients. The most common social media application usage during driving was Facebook 43 (36.4%), followed by Whatsapp 24 (20.3%), Google 19 (16.1%), and Instagram 15 (12.7%).Conclusion::This study provides evidence that social media usage while driving put the drivers and other road users' lives at high risk. The most common social media addiction while driving is Facebook and Whatsapp. So there is a need to make strict rules and penalties for using cell phone during driving so as to save the lives of drivers and other people using road.

Introduction: Milkfish is a potential source of animal nutrition, especially for supplying human protein needs. In the present paper, we provide complete data on nutrient content of milkfish that can be used as a reference for diet formulation and for the further processing of milkfish.
Methods: Proximate analysis, amino acid and fatty acid composition, and vitamin and mineral content of milkfish were determined.
Results: The results showed that milkfish contained high concentration of protein (24.18%) and high proportion of monounsaturated fatty acids as oleic acid (32.11%). The amino acid found in the highest concentration was glutamic acid (1.28%). The macro-minerals in the milkfish were calcium (Ca), magnesium (Mg), sodium (Na) and potassium (K). Among the micro-minerals present were iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn), and the main vitamins present include A, B1 and B12.
Conclusion: Based on their protein content, milkfish may be classified as a source of high protein. Glutamic acid which is the highest amino acid in milkfish as well as fatty acid content of oleic acid makes milkfish a healthful fish.

BACKGROUND: Chronic lymphocytic leukemia (CLL) exhibits profound heterogeneity in its clinical course. Its clinicohematological and cytogenetic features play a significant role in determining the clinical course and in predicting the treatment response and prognosis. In this context, 17p deletion is known to predict a poor prognosis, as these cases are refractory to conventional therapy. This study aimed to evaluate the clinicohematological characteristics, outcomes, and prognostic factors among CLL patients with and without del 17p in Pakistan. METHODS: This prospective observational study was conducted at the Department of Haematology, Armed Forces Institute of Pathology (Rawalpindi, Pakistan) between January 2013 and December 2017. Patients were diagnosed based on the International Workshop on Chronic Lymphocytic Leukaemia IWCLL criteria, their clinicohematological parameters were recorded, and cytogenetic analyses were performed. The time from diagnosis to treatment and the 2-year overall survival rate were also evaluated. RESULTS: We evaluated 130 CLL cases, including 24 patients (18.5%) with del 17p, who included 18 men (75%) and 6 women (25%). The median age was 68 years. Binet stage C was detected at the presentation in 16 patients (67%). Treatment was administered to 14 patients (70%) at a median interval of 11 months (range, 0–28 mo) after diagnosis. The overall response rate was 64.3%, the median event-free survival was 9 months (range, 1–23 mo), and the 2-year overall survival rate was 65%. CONCLUSION: Del 17p is relatively common in Pakistan, and patients harboring this deletion had poor treatment response and survival outcomes.

The present study was conducted to clarify the psychophysiological relaxation effects of viewing bamboo on university students. Forty healthy Chinese participants enrolled in this study to clarify the psychophysiological relaxation effects of viewing bamboo. The effects of visual stimulation using a pot both with and without a bamboo were recorded by measuring the student's blood pressure, EEG and STAI. We observed that viewing bamboo plants resulted in significantly lower systolic (female, P < 0.001; male, P < 0.001; P < 0.05) and diastolic (female, P < 0.001; male, P < 0.001; P < 0.05) blood pressures, but no changes in the pulse rate (female, P = 0.09; male, P = 0.07; P > 0.05) were observed. The results of the EEG analysis indicated brainwave variation (all P < 0.05) and lower anxiety scores (P < 0.01) after 3 min of viewing bamboo compared with the control. These findings indicate that visual stimulation with bamboo plants induced psychophysiological relaxation effects on adults.
