In this study COVID-19 effects on different aspects of life that how this virus created a mess in every discipline of life starting from a small tuck shop of a street to a huge business with a chain between different countries; and some preventive measures are also suggested. Not only mental healthiness as well as physical health of people was also disturbed to a large extent. People being quarantined did not do any practice and had nothing to do, their boredom made them mentally and physically inactive. For minimization the effect of this pandemic on mental healthiness, interventions were practiced and psychological support systems were developed to help mentally effected people; on the other hand, to improve physical health the hospital workers worked day and night in return they got affected too either mentally or physically. Many of the youngsters started alcohol consumption during quarantine. Because of the closure of educational institutes, the students were sent back to their homes where there was no proper guidance for them and they lost their interests in studies; and in a sense educational impact of COVID-19 was also unbearable. Agricultural system was affected badly and the whole world passed through a huge economic loss. The flights and traffic were blocked throughout the world, and it is the only positive impact that COVID-19 led to the environment by improving water and air quality as there was a remarkable reduction in the emission of greenhouse gases.

Water pollutants especially alcoholic based aromatic compounds are documented as emergent water pollutants and caused serious health problems for all living organisms. It is a major challenge for all researchers to synthesize effective adsorbents to eliminate these water pollutants. For this purpose, two MOFs were synthesized and characterized using SEM, FTIR, EDX and PXRD techniques. These MOFs exhibited excellent adsorption capacity for resorcinol and adsorption process was spontaneous, endothermic and proceeds with physiosorption as confirmed using thermodynamics data (∆H ads = 30.473 kJ/mol). Furthermore, separation-factor value was in the range of 0.0238–0.1312 for 30–100 ppm resorcinol concentration which represents that adsorption process was favorable. Langmuir and Pseudo 2nd order Models were best described which represented that chemisorption process also favored due to presence of –OH group and N-atom between adsorbent and adsorbate as well as monolayer adsorption-process is proceeded. Moreover, ion-exchange and electrostatic-interactions are the major interactions which are responsible for adsorption of resorcinol. Along with electrostatic-interactions, ion-exchange, hydrogen-bonding and π–π stacking/interactions are also accountable for adsorptive elimination of resorcinol. In summary we can conclude that MOFs are considered outstanding adsorbents for elimination of water pollutants to purify water, as water is very important for healthy life.

The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC’s 7.97 ×103mm-3, RBC’s 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

Present research work represents antiviral and antibacterial value of body fat of Saara hardwickii commonly called as spiny tailed lizard. Oil was extracted from body fats located in the ventral region of this animal using hydrocarbons e.g., n-hexane, methanol, butanol and ethyl acetate as a solvent. The antibacterial activity of lizard oil was tested against standard as well as multi-resistant lines ofEscherichia coli, Styphalococcus aureus, Pseudomonas aeruginosa and Proteus vulgaris alone and with antibiotic ampicillin. For antibacterial potential, Ethyl acetate and Butanol solvent extract showed best zone of inhibition (7mm) with P. aeruginosa and S. aureus respectively. For antiviral potential, Butanol and Methanol extract showed best HA (Hemagglutination) titer of 04 with NDV and IBV viral strain respectively. It is concluded that lizard oil has antimicrobial potential against different pathogens strains (virus, bacteria).

Teratogenic and embryotoxic effect of diclofenac sodium (DS) on different developmental stages of the chick-embryos was investigated by examining different parameters such as its mortality rate, hatching, morphological measurements, weighing its internal organs and calculation of different indices. Experiment was divided into four trials with different dose (0.1 mL, 0.2 mL, 0.3 mL in groups A, B, and C, respectively and group D received 0.3 mL saline solution (0.9% NaCl) and group E remained un-injected) administration and observation. Results of first and second trial showed statistically (p<0.01) significant difference in bodyweight, body-length, forelimb and hindlimb length between experimental and control groups. In third trial, diclofenac sodium administration showed a statistically (p0.05) when compared with the control groups. In trial 4, forelimb, hindlimb length, heart weight, CSI and HSI were statistically (p<0.01) significant. Body-length and liver weight were significant (p0.05). The mortality rate was increased with increase dose of DS and also affected the hatching. DS effect on chick embryos can be applied to humans because the early development of mammals and birds are closely related. So, it was concluded that DS should be used with caution during pregnancy especially during first trimester of pregnancy.
