Decadal trends in the exclusive breastfeeding practices among working Indian mothers: a multi-level analysis.

Background: Exclusive breastfeeding (EBF) is defined as feeding infants only breast milk of the mother or a wet nurse for the first six months, without additional food or liquids except the oral rehydration solution or drops/syrups of vitamins, minerals or medicines. The working status of women in developed countries adversely affects the EBF rates, which calls for an assessment in rapidly developing countries like India. Therefore, the primary aim of the present study is to determine the prevalence of EBF using the data from the National Family Health Surveys (NFHS 3, 4, 5) conducted between 2005 and 06, 2015-16 and 2019-21 to estimate the likelihood EBF according to mothers' employment status.

Understanding megasporogenesis through model plants: contemporary evidence and future insights.

The megasporangium serves as a model system for understanding the concept of individual cell identity, and cell-to-cell communication in angiosperms. As development of the ovule progresses, three distinct layers, the epidermal (L1), the subepidermal or the hypodermal (L2) and the innermost layers (L3) are formed along the MMC (megaspore mother cell). The MMC, which is the primary female germline cell, is initiated as a single subepidermal cell amongst several somatic cells.

Seaweed and a biocontrol agent and their effects on the growth and production of Brassica juncea: a sustainable approach.

Chemical fertilizers are crucial for increasing agricultural growth and productivity, but inorganic fertilizers can negatively impact agricultural systems. To address this issue, sustainable techniques like organic farming are being developed, which improve soil quality and nutritional status while preserving human safety. In the Botanical Garden, of Department of Botany at the University of Delhi, India, experiments on Brassica juncea were carried out over a three-year period in six micro plots, each measuring 10 square meters.

Prevalence of proximate risk factors of active tuberculosis in latent tuberculosis infection: A cross-sectional study from South India.

The prevalence of proximate risk factors for active tuberculosis (TB) in areas of high prevalence of latent tuberculosis infection (LTBI) is not clearly understood. We aimed at assessing the prevalence of non-communicable multi-morbidity focusing on diabetes mellitus (DM), malnutrition, and hypertension (HTN) as common risk factors of LTBI progressing to active TB. In a cross-sectional study, 2,351 adults (45% male and 55% female) from villages in the Kancheepuram district of South India were enrolled between 2013 and 2020.

Exploring the sister cells of embryo sac: developmental and functional attributes.

Synergids are metabolically dynamic cells of the egg apparatus and represent an important component of the female gametophyte. Besides directing the growth of the pollen tube towards the micropylar end of the embryo sac, these ephemeral structures make room for the pollen tube cytoplasm. The nature of chemotrophic substances that direct the growth of the pollen tube, the mechanism of degeneration of one of the synergids before fertilization and the molecular aspects of synergid morphogenesis have been studied in detail.

Seroprevalence of Strongyloides stercoralis infection in a South Indian adult population.

Background: The prevalence of Strongyloides stercoralis infection is estimated to be 30-100 million worldwide, although this an underestimate. Most cases remain undiagnosed due to the asymptomatic nature of the infection. We wanted to estimate the seroprevalence of S.

Inhibition of HIV-1 replication by balsamin, a ribosome inactivating protein of Momordica balsamina.

Ribosome-inactivating proteins (RIPs) are endowed with several medicinal properties, including antiviral activity. We demonstrate here that the recently identified type I RIP from Momordica balsamina also possesses antiviral activity, as determined by viral growth curve assays and single-round infection experiments. Importantly, this activity is at play even as doses where the RIP has no cytotoxic effect.

Influenza virus partially counteracts restriction imposed by tetherin/BST-2.

Influenza virus infections lead to a burst of type I interferon (IFN) in the human respiratory tract, which most probably accounts for a rapid control of the virus. Although in mice, IFN-induced Mx1 factor mediates a major part of this response, the situation is less clear in humans. Interestingly, a recently identified IFN-induced cellular protein, tetherin (also known as CD317, BST-2, or HM1.

Ribosome-inactivating proteins: current status and biomedical applications.

Ribosome-inactivating proteins (RIPs) are mainly present in plants and function to inhibit protein synthesis through the removal of adenine residues from eukaryotic ribosomal RNA (rRNA). They are broadly classified into two groups: type I and type II. Type I RIPs are a diverse family of proteins comprising a single polypeptide chain, whereas type II RIPs are heterodimeric glycoproteins comprising an A-chain (functionally equivalent to a type I RIP) linked via a disulphide bond to a B chain, mediating cell entry.

Ribosome inactivating proteins from plants inhibiting viruses.

Many plants contain ribosome inactivating proteins (RIPs) with N-glycosidase activity, which depurinate large ribosomal RNA and arrest protein synthesis. RIPs so far tested inhibit replication of mRNA as well as DNA viruses and these proteins, isolated from plants, are found to be effective against a broad range of viruses such as human immunodeficiency virus (HIV), hepatitis B virus (HBV) and herpes simplex virus (HSV). Most of the research work related to RIPs has been focused on antiviral activity against HIV; however, the exact mechanism of antiviral activity is still not clear.

Balsamin, a novel ribosome-inactivating protein from the seeds of Balsam apple Momordica balsamina.

Plant seeds, a rich source of proteins, are considered important for their application as functional ingredients in a food system. A novel ribosome-inactivating protein (RIP), balsamin was purified from the seeds of Balsam apple, Momordica balsamina. Balsamin was purified by ion exchange chromatography on CM Sepharose and gel filtration on superdex-75.
