The Himalayan shrew, Soriculus nigrescens Gray, 1842, belongs to the monotypic genus Soriculus, which is distributed mainly in the Himalayan region. Previous authors have studied its classification based on morphological and molecular data. However, no comprehensive study of the diversity and phylogeny of this species has been performed. In this study, we investigated the molecular phylogeny, genetic diversity, and species divergence of S. nigrescens based on one mitochondrial gene and three nuclear genes. A total of 124 samples from 27 sites in Southwest China were analyzed. Our molecular phylogenetic analyses and species divergence reveal non-monophyly of Soriculus, potentially representing two genera and three clades. Populations from Yunnan (Clade YN) represent the subspecies S. n. minors and should recover the full species status. Populations from Himalayas (Clade A) represent the species S. nigrescens, while populations from southeastern Nyenchen Tanglha Mountains and southern Himalayas (Clade B) represent a new cryptic and unnamed species. Species delimitation analyses and deep genetic distance analysis clearly support the species status of these three evolving clades. The putative new genus and cryptic species should be studied and identified in the future using a more extensive sampling combined with a comprehensive morphological and phylogenetic analysis.

A structural protein called keratin is often employed in the medical industry to create medication carriers. Process improvement, antioxidant, antibacterial, and adjuvant drug studies of synthetic bioactive keratin microparticles made from lipids and keratin derived from porcupine (Hystrix indica) quills are the main objectives of this study. After coating the keratin microparticles with lipids which were obtained from the same porcupine quills, the bioactive keratin microparticles were produced. The response surface technique was applied to optimize the conditions for extraction of the keratin protein and sizing of the keratin microparticles. An infrared spectroscopy was used to analyze the chemical shifts in compositions of keratin microparticles while the optical microscopy was used to measure the size of the keratin microparticles. The results of this work revealed that a yield 27.36 to 42.25% of the keratin protein could be obtained from porcupine quills. The keratin microparticles were sized between 60.65 and 118.87 µm. Through response surface optimization, mercaptoethanol and urea were shown to be the main variables which positively affected the yield and the size of the keratin protein. The lipid stacking on the keratin microparticles’ surface was confirmed by infrared spectroscopy. The 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulphonate) assay confirmed the keratin microparticle’s antioxidant activity of 29.83%. Compared to lipid alone, the antibacterial properties of the keratin microparticles against Escherichia coli—a gram-negative—and Staphylococcus aureus—a gram-positive—bacteria enhanced by up to 55% following the coating of the microparticles with the lipids. The pharmacological action against these bacterial species was further improved by the lipid-loaded erythromycin that was carried on the surface of keratin microparticles. This work has demonstrated the design and uses of the keratin microparticles obtained from porcupine quills for clinical applications.

This research was carried out to analyze variations in indoor and outdoor ozone concentrations and their health impact on local communities of megacities in Pakistan. For indoor ozone measurements, industrial units of an economic zone, Hattar Industrial Estate, Haripur, KPK, Pakistan, were selected. For outdoor ozone measurements, maximum and minimum peaks from different selected stations of three megacities (Islamabad, Abbottabad, and Haripur Hattar) in Pakistan were analyzed for paired comparisons. The tropospheric ozone levels were measured with the help of a portable SKY 2000-WH-O3 meter from December 2018 to November 2019. According to the findings of this investigation, the indoor ozone concentrations at Hattar Industrial Estate exceeded the permissible limit devised by the WHO. The highest concentration (0.37 ppm) was recorded in the month of May in the food industry, while the lowest concentration (0.00 ppm) was recorded in the cooling area of the steel industry in the month of December. For outdoor ozone concentrations, the maximum concentration (0.23 ppm) was detected in Islamabad in the month of March 2019, whereas the rest of year showed comparatively lower concentrations. In Haripur, the maximum concentration (0.22 ppm) was detected in the month of February 2019 and a minimum concentration (0.11 ppm) was found in the month of November 2019. In Abbottabad, the maximum concentration (0.21 ppm) was detected in the month of March 2019 and the minimum concentration was 0.082 ppm. Increasing tropospheric ozone levels might be harmful for local communities and industrial laborers in the winter season because of the foggy weather. In the Abbottabad and Hattar regions, since COVID infection is indirectly related to low temperature and high emission of gases may compromise the respiratory systems of humans. The results of the present study were shared with industrialists to set precautions for ambient air quality and support the adoption of low emission techniques in industries for the safety of labour and nearby residents.

Abstract The elegant water shrew, Nectogale elegans, is one of the small mammal species most adapted to a semi‐aquatic lifestyle. The taxonomy of the genus Nectogale has received little attention due to difficulties in specimen collection. In this study, we sequenced one mitochondrial and eight nuclear genes to infer the phylogenetic relationship of Nectogale. Phylogenetic analyses revealed two large clades within Nectogale. One clade represented N. elegans, and the other was regarded as N. sikhimensis. The split between N. elegans and N. sikhimensis dated back to the early Pleistocene (2.15 million years ago [Ma]), which might be relevant to the Qinghai‐Tibet Plateau (QTP) uplift. The morphological comparison showed several distinguishing characters within Nectogale: the shape of the mastoids, the first lower unicuspid (a1), and the second upper molar (M2). Overall, the molecular and the morphological evidences supported that the genus Nectogale consists of two valid species: N. elegans and N. sikhimensis.

The utilization patern of plant resources of Pin Punjal Mountanious range of Azad Kashmir and anthropogenic stress of the ecosystem was documented. A total of 150 species were recorded by the local people for various needs, such as, 19 species used as fruit and vegetables, 47 as medicinal, 26 as fuel wood, 12 as timber for furniture making, 32 as fodder for grazing of livestock, 4 as ornamental and 10 as aesthetic for cultural and religious activities. The anthropogenic pressure on the ecosystem was analysed by using principal components analysis (PCA) which resulted significant anthropogenic stressors on the natural resources of the area.

In this study we screened Viburnum grandiflorum for bioactive secondary metabolites and biological activity. Secondary metabolites were detected by phytochemical tests, and biological activity was confirmed through antimicrobial and anti-oxidant assays. Phytochemical screening (alkaloidal, tannins, terpenoids, flavonoids, anthraquinones, and glycosides) was performed with methanol, and aqueous and ethyl acetate extracts. Antibacterial activity against four bacterial strains — staphylococcus auries, Escherichia Coli, Bacillus subtillus, and salmonella typhi – were measured. Methanolic extract showed maximum inhibitory activity with diameter of zone of inhibition (11.66 mm), followed by n-hexane extract (9.33 mm) and then ethyl acetate extract. Four different fungi (Penicillium chrysogenum, Aspergillus flavus, Rhodotorula mucilaginosa, and Stachybotrys chartarum) were also tested against plant stem extract using different solvents. Dimethyl sulfoxide extract showed a maximum zone of inhibition at 20 mg/ml. Anti-oxidant activity of stem extract of Viburnum grandiflorum was evaluated by 1, 1-diphenyl2-picryl-hydrazyl (DPPH). Then we measured absorbance, and percentage activity at each concentration was found for three solvent extracts to get Ic50 values. These data support Viburnum grandiflorum as having enough potential to be used safely as an antimicrobial drug.
