Antimycolytic agents: fungistatic and fungicide

Published on: 6th May, 2022

Invasive fungal infections are described as a continuous and severe harm to human health and they are associated with at least 1.5 million deaths worldwide each year. Amphotericin B exerts its activity through hydrophobic interactions with cell membrane ergosterol, cause the rupturing or leakage of cell membrane. The antifungal azole medicine group is classified as imidazoles (clotrimazole, ketoconazole, miconazole) and triazoles (fluconazole, itraconazole, voriconazole, posaconazole, isavuconazole) that are named according to the number of nitrogen atoms in the azole ring. Flucytosine is a first-line treatment for the management of cryptococcal meningitis. The most routine adverse effects of fluconazole involve accelerated liver enzymes, gastrointestinal complaints, headache, and skin rash. If antacids, PPIs, H2 blockers administered together with ketoconazole medicines; they will reduce the blood levels of ketoconazole by increasing gastric pH because ketoconazole requires an acidic media for dissolution and systematic absorption. Griseofulvin ruptures mitotic spindle during metaphase by interacting with fungal microtubules-(-), fungal mitosis (metaphase arrest), adequate to block expansion of fungi (drug is static), preventing them from damaging.

Anthelmintic agents: vermicide and vermifuge

Published on: 6th May, 2022

OCLC Number/Unique Identifier: 9506575146

Helminthiasis is also known as worm infection, is any macroparastic disease of humans and other animals in which a part of the body is infected with parasitic worms known as helminths. Anthelmintic agents are medicines that used for treatment and inhibition of parasitic infections caused by helminths; which involve both flat worms, such as, flukes and tapeworms and round worms, such as, nematodes. Anthelmintics are categorized into groups depending on the basis of their identical chemical structure and mode of action. Thiabendazole, mebendazole, and albendazole belong to benzimidazoles group of antihelmenthic medicines. From benzimidazoles group of antihelmenthic, thiabendazole was first discovered in 1961 and already a mentioned number of more benzamidazoles were interpolated as wide spectrum anthelmintics. Praziquantel has a particular effect on the enveloping layer of trematodes and increases permeability of calcium ion influx leading to uncontrolled muscle contraction and paralysis. Praziquantel has a particular toxic effect on schistosome parasites, where its mode of action has been resulted more extensively than in cestodes. Coadministration of mebendazole with CYP450 inhibitors medications such as cimetidine, ketoconazole and etc may be increases plasma levels of mebendazole, by extending the half-life and decreasing plasma clearance.

Effectiveness of different cord care interventions on omphalitis prevention among neonates in Nakuru County Hospital, Kenya

Published on: 5th May, 2022

Background: Sepsis among newborns is common and a major cause of neonatal deaths in developing countries. Annually, about 4 million neonatal deaths occur around the world. Of these, more than 30% are caused by infections majority of which start as umbilical cord infections. Topical umbilical cord care can reduce omphalitis (umbilical cord infection) and neonatal mortality among newborns.Objective: This study aimed to compare the incidence of omphalitis in different cord care interventions (Dry, Chlorhexidine, and Alcohol) in Nakuru County, Kenya. Methodology: A randomized controlled trial was carried out between July 2018 and June 2019. A total of 540 newborns were randomly assigned to receive 1 of 3 cord care regimens; twice cord cleansing with 4% chlorhexidine (Group 1), twice cord cleansing with 70% alcohol (Group 2), and dry cord care (Group 3) as control. Results: The risk of omphalitis was significantly reduced in the chlorhexidine group than in dry and alcohol cord care groups. The incidence of omphalitis was 1.95 times more likely to occur among the dry cord care group [AOR = 1.95; 95% CI = 1.13-3.38; p = 0.017] compared to the chlorhexidine group. Similarly, babies in the alcohol group were nearly 2 times more likely to develop omphalitis [AOR = 1.98; 95% CI = 1.15-33.40; p = 0.014] compared to those in the chlorhexidine group.Conclusion and recommendation: Chlorhexidine topical cord care significantly reduces the risk of umbilical infection in neonates when compared to both topical alcohol application and dry cord care approach. It should be recommended to be used topically for the prevention of omphalitis in our setup.

Food applications of Aloe species: A review

Published on: 4th May, 2022

OCLC Number/Unique Identifier: 9507334452

Plants have a high concentration of biologically active molecules. Aloe plants tend to store water and important chemical constituents in their swollen and succulent leaves due to their ability to survive in hot and dry conditions, which makes them a unique source of phytochemicals. The Aloe leaf contains more than 200 nutritional substances, including vitamins, minerals, amino acids, and active enzymes. These constituents are analyzed as phytochemical screening (qualitative analysis) or proximate and mineral content analyses (quantitative analysis). Aloe is used as a food product and beverage ingredient. Functional and nutraceutical foods, edible coatings/films, Aloe species as cooked vegetables, and raw eating of Aloe species are how the Aloe plant is considered in food applications. The researchers reported edible Aloes for several species. However, it is not mean that all species of Aloe are edible. It is not only the leaves of Aloe that have nutritional values also other parts of the plant do. The study evaluated the nutritional value of Aloe flowers and their possible use as edible flowers. Aloe species are increasingly being incorporated into different health drinks, foods, and beverages due to the beneficial biological activities of the phytochemicals.

Harmonic oscillation picture of the free electron Zitterbewegung in vacuum

Published on: 3rd May, 2022

As shown e.g. in ref.[1] Zitterbewegung (trembling motion) of the free Dirac electron is generated if transitions between positive and negative energy states occur. Here we treat this effect in a single-mode configuration using a density matrix method. As compared with more elaborate conventional treatments, this method allows an easy estimate of the amplitude of the motion. The result is by predicted spreads of the free electron charge.

Treatment of perianal fistulae in crohn's disease with mesenchymal stem cells

Published on: 4th May, 2022

Crohn's disease is a chronic syndrome of the gastrointestinal tract that produces idiopathic inflammation. Approximately half of the patients develop abscesses and/or fistulas throughout their history that are located, mainly, in the perianal region. Current treatments are based on individualized plans that generally use combined pharmacology for symptomatic relief based on glucocorticoids, immunosuppressants or immunomodulators, antibiotics, anti-inflammatories, probiotics, and antibodies, or surgical therapies such as intestinal resections or ostomizations (colostomy and ileostomy) that tend to cause notable side effects in a considerable percentage of patients and a significant decrease in their quality of life.Perianal fistulas consist of abnormal tracts, inflammatory tunnels, or chronic tracts of granular tissue that connect two surfaces lined with epithelium, have an external hole in the skin that borders the anus, and an internal hole located inside it around the anal canal, rectus and sphincters. Treatment is a complex process that requires a multidisciplinary approach and the combination of several treatments. In the short term, the goal is to drain abscesses, reduce inflammatory and infectious processes, guard the fistulous tract with seton or lax lines, facilitate patency, and hinder new formations. In the long term, a total cure and the avoidance of complications that require surgery or the creation of intestinal stomas are pursued.For this reason, new effective remedies with fewer adverse effects continue to be investigated, one of the most promising being the use of mesenchymal stem cells for the regeneration and cure of perianal fistulas and the remission of symptoms. The present bibliographic review delves into this new therapy and analyzes the current state of the situation regarding its efficacy and safety.

Willingness to pay and sensory acceptability for minimally processed vegetables: behavior of consumers with different household incomes

Published on: 3rd May, 2022

Willingness to pay (WTP) and sensory acceptability for minimally processed (MP) vegetables were studied. A total of 116 participants of two different household incomes (HI) were considered. Two types of preparations (bags with whole vegetables and trays with MP vegetables), and two types of presentations (mix vegetables for soup and mix vegetables for salad), were evaluated. Low income (LI) participants offered more money in general than the medium-high income (MI) participants. However, the offers of the two preparations (soup and salad) did not show significant differences. The 4 samples (two preparations: soup and salad; and two presentations: bags and trays) had good sensory acceptability with values between 6.5 and 8.3, on a scale of 1-9. MI consumers had higher acceptability for mixed vegetables for soup than for salad vegetables; however, LI participants showed no difference between the types of preparation, observing for both samples (soup and salad) high acceptability. For both HI, Check All That Apply (CATA) questions showed that phrases such as “It is unreliable” and “I distrust how it was prepared” were associated with the trays, while the phrase “It takes time to prepare or cook” was associated with bags.

Review on epidemiology of bovine hemoparasites in Ethiopia

Published on: 29th April, 2022

A literature-based review was made to assess available information on bovine hemoparasites related to their epidemiology, distribution, and economic importance in Ethiopia. Babesiosis, anaplasmosis, cowdriosis, theileriosis, and trypanosomosis are the major hemo-parasitic disease of bovine in Ethiopia. Their adverse effects on the health of the animals can decrease production and productivity. Hemoparasites generally cause fever, anemia, jaundice, anorexia, weight loss, milk drop, malaise, swelling of lymph nodes, dyspnoea, diarrhea, nervous disorders, and death by affecting blood vessels and/or lymphatic system of the animal. Reports from different parts of the country displayed there is a high distribution of bovine hemoparastic disease throughout the country. Anaplasmosis, Babesiosis (redwater), Ehlichiosis (Heartwater), Theileriosis, and Trypanosomosis are the major hemoparasitic diseases with heavy economic losses. Their mode of transmission was by arthropod vectors ticks and flies. Applying effective vector control and using vaccines drugs are the two most important control methods for hemoparasites diseases. Also having knowledge of parasite life cycles, their biological vector, and the immune response of bovines to vectors and parasites were also used in the successful application of control strategies. Creating awareness of the mode of transmission, method of control, and prevention of hemoparastic disease of bovine to livestock owners were warranted to decrease the effect of the disease.

ACE2 and TMPRSS2 polymorphisms and the development of COVID-19: a review of the literature

Published on: 28th April, 2022

SARS-CoV-2 is a virus that has a positive-sense, single-stranded RNA genome that encodes 4 structural proteins, the main one being the S protein (Spike) responsible for mediating with ACE2 and TMPRSS2 for entry into the host cell. The study of single nucleotide polymorphisms (SNPs) of ACE2 and TMPRSS2 can elucidate their possible intervention in the action of the protein, its activity, and the gene expression of encoding these enzymes, which may increase susceptibility to viral infection. From this, literature searches were carried out until December 2021, listing 11,820 publications for literary analysis on the described genetic variations of these protein structures, as well as their relation and influence on the pathology. It was possible to conclude that there is a great influence exerted by genetic variability in ACE2 and TMPRSS2 increasing the ability of the virus to bind to the host cell and the development of COVID-19 with complications.

Treatment of advance keratoconus using donor bowman layer: the zaman technique of bowman layer transplantation (Type I & Type II)

Published on: 6th May, 2022

Commonly referred to as an ecstatic, non-inflammatory disease, Keratoconus, usually bilateral and asymmetric, is characterized by progressive steeping and thinning of the cornea. This results in irregular astigmatism which compromises vision [1,2]. Traditionally, early Keratoconus stages have been treated by prescribing a hard contact lens to obtain a regular anterior optical surface. This tendency was discontinued when contact lens intolerance in advanced stages required the use of penetrating keratoplasty (PKP) or deep anterior lamellar Keratoplasty (DALK). An alternative technique of corneal cross-linking was designed in 2003 as a treatment option for keratoconus. The cornea measured at least 400 um thickness after epithelium removal and pre-operative maximum keratometry (Kmax) measured 58D or less. As a result, no corneal transplantation was required or postponed [3].
