Characterization of the indigenous goat production system in Asossa zone, Benishangul Gumuz region, Ethiopia

Most of the livestock population in Asossa zone is comprised of indigenous goats, which have remarkable socioeconomic relevance to the society. This study aimed to generate information on the production system and production constraints of goats in the study area. The study was conducted based on a household survey in which 192 householdswere purposively sampled. The households were located in Sherkole, Kurmuk and Menge districts that have a high goat population in Asossa zone. Data were recorded inMS Excel data sheet and analyzed using SAS. A chi-square and GLM procedure of SAS was used to test significant differences among categorical and quantitative variables. The primary reason for keeping goats was for cash income with an index value of 0.46, 0.34 and 0.31 for Sherkole Kurmuk and Menge districts, respectively. Milk was the second purpose for rearing goats, with a ranking index value of 0.29, 0.30 and 0.30 for Sherkole, Kurmuk, and Menge districts, respectively. Grazing on natural pasture was the major feed source for goat production in the three districts (with an index of 0.86, 0.91 and 0.0.87 for Sherkole, Kurmuk and Menge districts, respectively). Although the majority of households (59 %, 75% and 62.5% in Sherkole, Kurmuk, and Menge districts, respectively) used yard type of housing, the number of households that used this type of housing was significantly different (p<0.05) among the three districts. Majority of goat owners used an uncontrolled type of mating that accounts 92.2%, 89.1% and 85.9% in Sherkole, Kurmuk, and Menge districts, respectively. Feed shortage (with ranking index value of 0.30, 0.34 and 0.28 in Sherkole Kurmuk and Menge districts, respectively) and water shortage (with ranking index value 0.21, 0.23 and 0.22 in Sherkole Kurmuk and  Menge districts, respectively) were the first and second goat production constraints. Age at sexual maturity was 7.52 months for males and 7.84 months for female goats in this region. Goats play a multi-functional role for the community by adapting to the different constraints that need intervention mechanisms from responsible bodies to boost the productivity of the sector.Key words: constraints, Ethiopia, feed, housing, indigenous goats, reproductive performance, production system, wate

Regulators of G protein Signaling (RGS) proteins (version 2020.4) in the IUPHAR/BPS Guide to Pharmacology Database

Regulator of G protein Signaling, or RGS, proteins serve an important regulatory role in signaling mediated by G protein-coupled receptors (GPCRs). They all share a common RGS domain that directly interacts with active, GTP-bound Gα subunits of heterotrimeric G proteins. RGS proteins stabilize the transition state for GTP hydrolysis on Gα and thus induce a conformational change in the Gα subunit that accelerates GTP hydrolysis, thereby effectively turning off signaling cascades mediated by GPCRs. This GTPase accelerating protein (GAP) activity is the canonical mechanism of action for RGS proteins, although many also possess additional functions and domains. RGS proteins are divided into four families, R4, R7, R12 and RZ based on sequence homology, domain structure as well as specificity towards Gα subunits. For reviews on RGS proteins and their potential as therapeutic targets, see e.g. [160, 377, 411, 415, 416, 512, 519, 312, 6]

The Concise Guide to PHARMACOLOGY 2023/24:Introduction and Other Protein Targets

The Concise Guide to PHARMACOLOGY 2023/24 is the sixth in this series of biennial publications. The Concise Guide provides concise overviews, mostly in tabular format, of the key properties of approximately 1800 drug targets, and about 6000 interactions with about 3900 ligands. There is an emphasis on selective pharmacology (where available), plus links to the open access knowledgebase source of drug targets and their ligands (www.guidetopharmacology.org), which provides more detailed views of target and ligand properties. Although the Concise Guide constitutes almost 500 pages, the material presented is substantially reduced compared to information and links presented on the website. It provides a permanent, citable, point-in-time record that will survive database updates. The full contents of this section can be found at http://onlinelibrary.wiley.com/doi/10.1111/bph.16176. In addition to this overview, in which are identified 'Other protein targets' which fall outside of the subsequent categorisation, there are six areas of focus: G protein-coupled receptors, ion channels, nuclear hormone receptors, catalytic receptors, enzymes and transporters. These are presented with nomenclature guidance and summary information on the best available pharmacological tools, alongside key references and suggestions for further reading. The landscape format of the Concise Guide is designed to facilitate comparison of related targets from material contemporary to mid-2023, and supersedes data presented in the 2021/22, 2019/20, 2017/18, 2015/16 and 2013/14 Concise Guides and previous Guides to Receptors and Channels. It is produced in close conjunction with the Nomenclature and Standards Committee of the International Union of Basic and Clinical Pharmacology (NC-IUPHAR), therefore, providing official IUPHAR classification and nomenclature for human drug targets, where appropriate.</p

Microglia Phenotypes in Aging and Neurodegenerative Diseases

Neuroinflammation is a hallmark of many neurodegenerative diseases (NDs) and plays a fundamental role in mediating the onset and progression of disease. Microglia, which function as first-line immune guardians of the central nervous system (CNS), are the central drivers of neuroinflammation. Numerous human postmortem studies and in vivo imaging analyses have shown chronically activated microglia in patients with various acute and chronic neuropathological diseases. While microglial activation is a common feature of many NDs, the exact role of microglia in various pathological states is complex and often contradictory. However, there is a consensus that microglia play a biphasic role in pathological conditions, with detrimental and protective phenotypes, and the overall response of microglia and the activation of different phenotypes depends on the nature and duration of the inflammatory insult, as well as the stage of disease development. This review provides a comprehensive overview of current research on the various microglia phenotypes and inflammatory responses in health, aging, and NDs, with a special emphasis on the heterogeneous phenotypic response of microglia in acute and chronic diseases such as hemorrhagic stroke (HS), Alzheimer&rsquo;s disease (AD), and Parkinson&rsquo;s disease (PD). The primary focus is translational research in preclinical animal models and bulk/single-cell transcriptome studies in human postmortem samples. Additionally, this review covers key microglial receptors and signaling pathways that are potential therapeutic targets to regulate microglial inflammatory responses during aging and in NDs. Additionally, age-, sex-, and species-specific microglial differences will be briefly reviewed
