A Review on the Ethnomedicinal Plants Used in Zimbabwe for the Treatment and Management of Skin Conditions: Perspectives on Pharmacological and Toxicological Evaluation

Received: 05 March 2025;  Published: 19 August 2025;  doi: 10.21926/obm.icm.2503036

Abstract

Medicinal plants remain central to healthcare in Africa, where up to 80% of the population relies on traditional remedies to manage a range of health conditions, including skin ailments. In Zimbabwe, the country's rich biodiversity and favourable agroecological zones support a diverse range of ethnomedicinal plants. However, much of the knowledge surrounding these plants remains dispersed and scientifically under-evaluated. This review consolidates evidence from ethnobotanical surveys, peer-reviewed research, and g [...]

Morpholine-Based Novel Ionic Liquid for Synthesis and Characterization of Triazolidinethiones and Their Biological Properties

Received: 03 December 2022;  Published: 12 March 2023;  doi: 10.21926/cr.2301011

Abstract

Keeping the green chemistry approach in mind we have synthesized a novel morpholine-based ionic liquid [NBMMorph]+Br-. The structure of Ionic liquid was confirmed by spectral techniques viz. IR, 1H NMR, and 13C NMR, analysis. The synthesized novel IL [NBMMorph]+Br- was utilized to prepare 1,2,4-triazolidine-3-thiones of biological significance. The [NBMMorph]+Br- IL shows excellent catalytic activity, and a simple filtration technique can separate the thiazolidinedione products. The structure of the synthesized com [...]

hTERT Promoter Regulation by Differentiation Mechanisms vs Telomerase Activity in Somatic, Embryonic, and Cancerous Cells

Received: 02 February 2019;  Published: 04 April 2019;  doi: 10.21926/obm.geriatr.1902045

Abstract

Telomere shortening in the somatic cells is one of the most well-documented factors of cellular ageing. Telomeres are composed of tandem hexanucleotide repeats that protect cells from unwanted recombination mechanisms, secure the ends of chromosomes and their stability, and are responsible for limited division capacity. Telomerase is an enzymatic ribonucleoprotein complex, present in embryonic cells, adult stem cells, and germinal progenitors, whose function is to extend the telomeres length by adding the lost tand [...]

Estimating Met-Ocean Parameters during a Tropical Cyclone for Marine Science and Engineering

Received: 16 April 2021;  Published: 16 June 2021;  doi: 10.21926/jept.2102025

Abstract

During a tropical cyclone (TC) worldwide, the Regional and Mesoscale Meteorological Branch (RAMMB) of NOAA/NESDIS (http://rammb.cira.colostate.edu/) issues real-time TC surface wind analyses. The purpose of this article is to provide value-added estimations of several meteorological and oceanographic (met-ocean) parameters including overwater friction velocity and turbulence intensity, variation of the wind speed with height, significant wave height, peak or dominant wave period, wind-driven currents and wind-stres [...]

The Potential of Chickpea (Cicer arietinum L.) for Anti-Osteoporotic Agent in Post-Menopausal Women: A Systematic Review of In Vivo Study

Received: 09 April 2024;  Published: 23 August 2024;  doi: 10.21926/rpn.2403012

Abstract

This systematic review aimed to analyze the in vivo study of the anti-osteoporotic activity of chickpeas. A comprehensive search for English language papers published between January 2013 and December 2023 using the keywords chickpea or Cicer arietinum, anti-osteoporotic activity or anti-osteoporotic effect, chickpeas and anti-osteoporotic activity, Cicer arietinum and antiosteoporotic activity and their synonyms yielded 3566 results from PubMed, ScienceDirect, SpringerLink and Google Scholar. Articles were screene [...]

Multidrug-Resistant Bacterial Infections before and after Liver Transplantation

Received: 29 March 2020;  Published: 18 May 2020;  doi: 10.21926/obm.transplant.2002110

Abstract

Bacterial infection represents a common event in the natural history of cirrhosis, especially in patients with end-stage liver disease. An episode of bacterial infection may significantly modify a patient’s outcome in the setting of liver transplantation (LT) by impairing hepatic and extrahepatic organ functions, both in pre-operative and post-operative phases. Infections caused by multidrug-resistant organisms (MDRO) are increasing in cirrhosis due to high antibiotic exposure and hospitalizations. This issue is pa [...]

Gender Differences in Manual, Electro, and Laser Acupuncture

Received: 08 January 2020;  Published: 14 January 2020;  doi: 10.21926/obm.icm.2001003

Abstract

Acupuncture, being a unique method, is a millennia-old tradition in the field of Chinese medicine. However, it is surprising that there are very few scientific publications on acupuncture and its gender-specific effects. This article summarizes the previous work from the perspective of both Western and Eastern medicine, involving manual acupuncture, electro-acupuncture, and modern innovative laser acupuncture. There is scientific evidence that future gender-specific considerations should be included in the assessme [...]

Combination of the Hansemann-Boveri, Warburg, and Knudson Theories of Cancer, Based on Failure of Missegregation Damage Mitigation

Received: 17 July 2019;  Published: 03 December 2019;  doi: 10.21926/obm.genet.1904100

Abstract

Hansemann-Boveri’s aneuploidy theory, the Warburg effect, and the Knudson hypothesis can be viewed as different aspects of a single theory of cancer. In this, the extremely common chromosome missegregation may be the underlying cause. Chromosome missegregation is mitigated via several mechanisms. Cancer can occur only when all of these mechanisms have been inactivated in a single cell line, typically by mutation. There are at least five different repair mechanisms, implying a hit-factor of at least five. These miti [...]

Energy Storage and Installed Wind Capacity Requirements for the Substitution of Fossil Fuels in the Electricity Generation Sector

Received: 19 April 2021;  Published: 10 September 2021;  doi: 10.21926/jept.2103040

Abstract

The impending adverse effects of Global Climate Change encourages the substitution of fossil fuels with non-carbon sources for electricity generation. However, while fossil fuel power plants may generate electric power at demand, the most abundant renewable energy sources-wind and solar-are intermittent or periodically variable. This necessitates the development of adequate energy storage at the utility/grid level. Using actual data for the hourly energy demand in the ERCOT electricity grid, this study examines the [...]
