Cutaneous photodamage is incited via exposure of ultraviolet‐B (UV‐B) radiation to skin, characterized by the manifestation of oxidative stress, inflammation, collagen degradation and apoptosis which translates to external aging signs such as wrinkle formation and leathery skin appearance. Meanwhile, it increases cellular susceptibility to photocarcinogenesis. Several studies have accumulated evidence...
Wild vegetables can contribute to people’s food security and health. In northwest Pakistan, almost 40% of the households are classified as food insecure, due to increasing population and natural and man-made catastrophes. There is an urgent need to get an overview of still existing practices of wild vegetable use and to incorporate such knowledge into agricultural policies. The present study, therefore,...
In a greenhouse experiment using sand columns, sorghum and pearl millet were grown and spiked with metal solutions of Cu, Cd, and Cr in two concentrations. The chelating agent EDTA was applied to one-month-old plants and metal mobilization was observed through uptake by the plants or leaching through the columns during a period of one month. Growth was much better in pearl millet than sorghum under...
This study is intended to scrutinize the consequence of extraction conditions of Lawsonia Inermis (henna) leaves on the color strength values of dyed fabric. Extraction pH, M:L ratio, and time were optimized using central composite design (CCD) under response surface methodology (RSM). We investigated how the maximum colour strength values were obtained at pH 6.64 in about 78 minutes extraction with...
This paper analyzes a phytosociological study and urbanization in Regi Model Township (RMT) in Peshawar, Pakistan. The study was conducted during spring 2015 and a total of 32 plant species were identified belonging to 19 families. The Asteraceae family had the highest number of species 5 spp. while Fabaceae, Polygonaceae, and Brassicaceae had 3 spp. each. Poaceae and Solanaceae had 2 spp. each, while...
This study looks at using partially purified peroxidase extracted from peels of sweet lime (Citrus limetta) for decolorizing textile industry effluent. The ideal pH and thermal conditions of the enzyme were 7 and 35ºC. The Km and Vmax for guaiacol were 0.66 mM and 6666 μmol/mL/min, respectively. We found that sweet lime peroxidase was very effective in decolorizing textile industry effluent. Almost...
Invertase has a vital role in ethanol fermentation, especially on sucrose-containing media. In this study, catabolite-resistant mutants of Saccharomyces cerevisiae were isolated through gamma ray mutagenesis with improved productivity of ethanol and invertases. Enzyme productivity of mutant yeast was compared with that of the parent. Various fermentation parameters were optimized, including substrate...
This study focuses on evaluating total phenolic contents (TPC) in Taraxacum officinale (L.), a member of the family Asteraceae (compositae). The TPC were estimated by Folin-Ciocalteu’s reagent and gallic acid was taken as standard. The amount of phenolics was communicated as gallic acid equivalent (GAE). The TPC varied from 41.47 mg/g to 691.6 mg/g in the Taraxacum officinale (L.) extracts. The maximum...
An enormous amount of waste material (sludge) generated from paper and pulp industries is either dumped or incinerated. However, this pulp is an enriched source of macronutrients and can be employed on agricultural land to improve its fertility. The current study was therefore performed to analyze phosphorus (P) and calcium (Ca) by flame photometer, nitrogen (N) by Kjeldahl method, and magnesium (Mg)...
Spectral conversion of the sunlight has been proposed as a method for enhancing the efficiency of photovoltaic devices, which are limited in current production by the mismatch between the solar spectrum and the wavelength range for efficient carrier generation. For example, the photo current can be increased by conversion of two low-energy photons (below the band gap of the absorber) to one higher-energy...
