With only three published reports, the genus Chroogomphus (Boletales, Gomphidiaceae) is poorly studied in Pakistan. During recent sampling events in Khyber Pakhtunkhawa province, Pakistan, several collections of Chroogomphus were made, representing undescribed taxa. Based on morphological and molecular data, two new species are described: Chroogomphus pakistanicus and C. pruinosus. We present a description and illustrations for both taxa. A molecular phylogenetic reconstruction, based on the internal transcribed spacer (ITS1–5.8S–ITS2) barcode region, shows that C. pakistanicus and C. pruinosus are placed in two different subgenera of Chroogomphus (subg. Chroogomphus and subg. Siccigomphus, respectively).
Rhodocollybia utrorensis sp. nov. is described from the Utror valley, Pakistan. It is characterized by a dull brown pileus with a low umbo and inrolled margin, adnate lamellae with wavy margin, presence of pleurocystidia and inamyloid basidiospores. Both morpho-anatomical features and phylogenetic analysis based on ITS nrDNA sequence indicate Rhodocollybia utrorensis is a new species. This is the first report of the genus Rhodocollybia from Pakistan.
Background: Globally, medicinal plants are widely used to treat ailments due to their safety, accessibility and efficacy.
Objectives: The objective of this study was to determine in vivo neuroprotective effect of methanolic extract of seeds of Cydonia oblongaagainst streptozotocininduced diabetes in rats, as this research has not been reported previously.
Methods: Methanolic extract (100, 150 and 200 mg/kg b.w) was administered for 21 days to diabetic rats. Total protein content, glutathione-S-transferase (GST) specific activity, total glutathione level (tGSH), catalase activity (CAT), malondialdehyde (MDA) level, superoxide dismutase (SOD) level and acetylcholinesterase (AChE) activity were determined in the brain homogenate.
Results: C. oblonga seeds extract showed a significantly (*p < 0.05) increased in GST activity, tGSH level, CAT activity and level of SOD. While MDA levels and AChE activity were decreased in comparison with streptozotocin-treated group. Histopathological examination also showed a marked improvement in the morphology of brain tissues.
Conclusion: It is concluded that the methanolic extract of C. oblonga seeds has the potential to protect the brain against streptozotocin-induced neurotoxicity by reducing oxidative stress and is beneficial for cognitive improvement in diabetic patients.

The study aimed to examine the effect of solitary on depression and the well-being of older adults residing in old homes. The sample comprised of older adults residing in old homes (N = 100). Solitude Scale, Depression subscale of Depression, Anxiety, and Stress Scale and Short Warwick Edinburg Mental Well-Being Scale were applied on the older adults. Linear Regression analysis showed that solitary positively predicted depression in older adults residing in old homes, whereas solitary negatively predicted well-being in older adults residing in old homes. The findings of this study can be used to improve the mental health of older adults residing in old homes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
