In the studies to know the feeding pattern of various species of mosquitoes, a total of 7461 specimens comprising of Anopheles culicifacies (150), An. stephensi (61), An. subpictus (990), An. annularis (572), Culex quinquefasciatus (5217) and C. vishnui group (471) of mosquitoes were collected from different biotopes of selected localities in Delhi and environs during all the months of the year. The mosquito blood samples were processed by Gel diffusion technique to know the source of blood meal. Results of study revealed that the mosquito species tested in the study were by and large zoophilic and opportunistic feeders. The feeding behaviour was found to be highly influenced by biotopes from where the mosquitoes were collected, village and areas, different climatic seasons, sleeping behaviour of human beings and availability of alternative hosts particularly animal population. Overall anthropophilic index was found to be 24.66% for An. culicifacies, 20.96% for An. stephensi, 16.93% for An. subpictus, 9.96% for An. annularis, 26.33% for C. quinquefasciatus and 36.39% for C. vishnui group of mosquitoes. Feeding behaviour towards other animals viz: bovine, goat, dog, pig and bird for all these mosquito species in different months and biotopes e.g. human dwellings, cattle sheds and mixed dwellings; in different months and seasons of the year have been presented.

Tooth replacement of the filter-feeding pterosaur Forfexopterus and its implications for ecological adaptation.

A "comb-dentition", characterized by long, needle-like, and closely-spaced teeth, is found in the ctenochasmatid pterosaurs as an adaptation for filter-feeding. However, little is known about their tooth replacement pattern, hindering our understanding of the development of the filter-feeding apparatus of the clade. Here, we describe the tooth replacement of the pterosaur Forfexopterus from the Jehol Biota based on high-resolution X-ray Computed Tomography (CT) reconstruction.

The aim is to unveil the useful value of breastfeeding for lactating women in a prison environment, based on Max Scheler's axiological perspective. This work was a qualitative, developed in a prison unit in Rio de Janeiro, where seven lactating women were interviewed. The phenomenological interview was used for data collection, while Laurence Bardin's content analysis was used for data analysis and treatment.

The broader use of botanical pesticides has been limited by shorter residual activity on plants, slower onset of action, and higher costs compared with conventional pesticides. These challenges could be overcome by the development of simple, cost-effective, and long-lasting preventive nanocomposites for botanical pesticides. In this study, we successfully developed a low-cost ethyl cellulose (EC)-based delivery system for the botanical pesticide osthole (OST), designed to provide extended preventive protection against infestations.

Background: This study aimed to investigate the effects of oral semaglutide on the changes in food preference of Japanese patients with type 2 diabetes.
Methods: This retrospective multicenter study included 75 patients with type 2 diabetes who received oral semaglutide. The primary outcome was the change in the score of brief-type self-administered diet history questionnaire (BDHQ) score 3 months after the initiation of oral semaglutide treatment.

Objective: To investigate the effects of light fasting diet therapy, including flaxseed powder supplementation, on lipid metabolism and sex hormone levels in patients with polycystic ovary syndrome (PCOS) combined with infertility.
Methods: A total of 104 PCOS patients with combined infertility were divided into the control group ( = 52) and intervention group ( = 52) using a random number table method. Over a two-month study period, the control group received light fasting diet therapy with rice flour as a placebo, while the intervention group received light fasting diet therapy supplemented with flaxseed powder.
