Closure of Post-infarct Basal Ventricular Septal Defect by Using an Atrial Septal Defect Closure Device: A Case Report
Published on: 25th November, 2024
Ventricular Septal Defect, also known as VSD is a rare and life-threatening complication associated with MI. Therefore, it should be immediately diagnosed and treated. Transcatheter closure of the ventricular septal defect is a new alternative treatment approach compared to surgery. In this case, we presented a patient with post-infarct basal ventricular septal defect whose ventricular septal defect was closed using an atrial septal defect closure device. The ability to successfully close such a large defect via catheter is promising for the treatment of patients with VSD.

Worldwide, Canine Distemper Virus (CDV) infection is a highly prevalent disease with high morbidity and mortality. CDV causes a multisystemic disease in a wide range of hosts including 9 families of mammals among them some primates, cetaceans and numerous carnivores. It presents a high tropism for lymphoid, neurological and epithelial tissue, leading to an infection of almost all systems, so the clinical signs observed are very varied. The diagnosis is made based on the clinical presentation of the disease, which considers a variety of signs and must be confirmed by a laboratory diagnostic method. The molecular technique called Reverse Transcription Polymerase Chain Reaction (RT-PCR) has been used to characterize viral strains based on the basis of genetic differences on the hemagglutinin (H) gene of CDV has allowed the identification of 14 circulating lineages in the world. Two lineages, namely the America-1 and the Europe-1/South America-1 have been described in Chile. The goal of this work was to implement a multiplex RT-PCR protocol, which was built on the in silico design of primers based on the H gene nucleotide sequences stored in the Genbank® database. This method was capable of detecting the previously described two circulating genetic lineages of CDV in a differential way providing a supporting diagnostic tool for epidemiological studies in the country. These results suggest that the primers described here are extremely selective for the above-mentioned lineages. In addition, our initial screening indicated that most analyzed clinical samples corresponded to the America-1 lineage, stressing the need for a continuous surveillance in order to properly address the prevalence of both lineages in Chile.

A study on growth and carcass performance was conducted to evaluate the effect of Balanites aegyptiaca seed cake meal (BASCM) as a substitute for groundnut cake in the diet of growing rabbit. Five experimental diets were formulated representing the following treatments: T1, T2, T3, T4 and T5 respectively. T1 (0% BASCM) was served as the control diet, while T2, T3, T4 and T5 contained 25%, 50% 75% and 100% BASCM respectively. A total of 100 weaner rabbits of mixed breeds were purchased from the National Animal Production Research Institute (NAPRI), Zaria, Nigeria. The rabbits were fed the control diet during the one week of adjustment period. They were given vitalyte as anti-stress and were dewormed using ivermectin, at the end of one week of adjustment; the rabbits were housed in different hutches and fed their respective experimental diet for one month. Each treatment contained 20 rabbits and these treatments’ (T1-T5) each were replicated in four portions and each portion had five rabbits each. Results showed that all the parameters were significantly different (P<0.05) among the treatment groups. Balanites aegyptiaca seed cake meal can replace groundnut cake at 25% level inclusion without adverse effect on the rabbit physiology.

Roux-en-Y Gastric Bypass surgery is superior to medical treatment for short- to medium-term remission of Type 2 diabetes (T2DM) [1]. Recent research indicates that the improvements in insulin sensitivity following bariatric surgery are associated with elevated circulating bile acid concentration and remodeling of gut microbiota [2]. Gut microbiome can be considered as a target of dietary interventions or medicines to prevention/treatment of hyperglycemia in T2DM. Since, the glucose-lowering effects of metformin are mediated by changes in the composition and function of gut microbiota [3,4].

Exploring the Complexity of Protein Structure Determination Through X-ray Diffraction
Published on: 21st November, 2023
The determination of a protein structure by using X-ray diffraction encompasses a series of sequential steps (including gene identification and cloning, protein expression and purification, crystallization, phasing model building, refinement, and validation), which need the application of several methodologies derived from molecular biology, bioinformatics, and physical sciences. This article thoroughly examines the complicated procedure of elucidating protein structures within plant biology, using X-ray diffraction as the primary methodology. Commencing with the gene identification process and progressing toward crystallography, this article explores the many obstacles and achievements in acquiring diffraction pictures and their subsequent conversion into electron density maps. The ensuing phases of model construction, refinement, and structural validation are thoroughly examined, providing insight into the inherent complexity associated with each stage. The paper also discusses the critical component of understanding the resultant model and scrutinizing its biological significance. By comprehensively examining these stages, this article presents a nuanced comprehension of the intricate procedure in ascertaining protein structures within plant biology. It offers valuable insights into the obstacles encountered and the biological importance of the acquired structural data.
Burden of hearing loss in Subsaharan Africa: Snapshot from an ENT clinic in Nigeria
Published on: 31st December, 2019
OCLC Number/Unique Identifier: 8512989994
Background: Disabling hearing loss is a prevalent public health issue, with significant impact on patients’ communication. The disability associated with hearing loss depends on the severity of the hearing loss. There are limited rehabilitative measures in resource challenged environment. This study assesses the incidence, the factors for hearing impairment and the management outcome.
Methods: A descriptive three-year chart review of patients managed for hearing loss in a tertiary health center in a developing country. The data collected include demographic data, clinical presentation and risk factors for hearing loss, audiometric reports, rehabilitative measures and management outcome.
Results: The patients with ear symptoms managed within the study period were 1350, of whom 498 (36.8%) had hearing loss of varying degrees. These included 145 (29.1%) males and 353 (70.9%) females with male to female ratio of 1:2.4. The age ranged from 8 to 80 years (median age of 35.7). Disabling hearing loss in the better-hearing ear occurred in 216 (43.4%) of cases. Increasing age and chronic supportive otitis media were associated with disabling hearing loss. The hearing thresholds improved with hearing aids and ear surgical procedures; nonetheless the patients’ rehabilitation was impaired by limited resources.
Conclusion: There is poor rehabilitation of people with hearing loss, though management outcome is commendable in a few of them. Health education will reduce the risk factors for disabling hearing loss and improved rehabilitative measures are needed for these individuals.
The impact of geographical origin on specific properties of pine honey

OCLC Number/Unique Identifier: 7286424595
Pine honey represents the major type of honey produced in Greece. In that sense, the aim of the present study was to investigate if specific physicochemical and bioactive properties could serve as markers of its geographical origin. For this purpose, forty pine honey samples were collected during harvesting years 2011 and 2012 from Halkidiki and Thassos, the well-known pine honey producing areas in Greece. Physicochemical parameters taken into account, using conventional and literature cited methods, were: pH, CIE colour parameters L*,a*,b*, and browning index. Furthermore, colour intensity and the in vitro radical scavenging activity were estimated by the application of spectrometric assays. Results showed that, pine honeys exhibited statistically significant differences (p<0.05) in pH, colour intensity, and radical scavenging activity, depending on geographical origin. On the basis of radical scavenging activity results obtained, pine honeys proved to have a high in vitro antioxidant “character’’. Finally, perfect Pearson’s correlations (r=1) at the confidence level p<0.01 were obtained for the sets: pH-browning index, pH-radical scavenging activity, and browning index -radical scavenging activity, with respect to geographical origin.

Efficient Sequential Chromatographic Purification of a Recombinant Nanobody-Fc Fusion Designed for Treatment of Severe Fever with Thrombocytopenia Syndrome
Published on: 29th January, 2025
Severe fever with thrombocytopenia syndrome (SFTS) is caused by a virus that induces acute infections. Despite its expansion beyond China, where it first appeared in 2009, no specific drug exists to treat the disease. The discovery that antibodies targeting the SFTS virus surface glycoprotein (Glycoprotein N, GN) significantly enhance patient survival has driven the development of antibodies, particularly nanobodies. Nanobodies targeting the GN protein are a promising therapeutic approach. This paper presents a systematic study of the purification process for a recombinant nanobody-Fc fusion designed to treat the SFTS virus HB29. The study evaluated a sequential purification approach using affinity (AFF), ion exchange (IEC), and hydrophobic interaction chromatography (HIC) techniques to gradually remove impurities. The results demonstrate that this approach achieves an overall yield of more than 50% and a total purity of 95%. Efficient nanobody purification methods, as outlined here, can pave the way for novel treatments to manage this disease.
