Published: May 2021

Microorganisms that are capable of spoiling the product during chill storage as well as several foodborne pathogens can be present in frozen snacks. The present study attempted to investigate the presence of microbial contaminants along with their antibiotic resistance pattern in frozen snacks. In this regard, a total of 15 ready-to-fry frozen chicken-based snack items including three each of chicken pops, chicken samosa, chicken lemongrass lollypop, chicken nuggets and chicken meatball were collected from super shops of Dhaka, Bangladesh. Microbiological analysis revealed that all the samples were highly contaminated with total viable bacteria and fungi in an average of 6 and 4 log cfu/g, respectively which exceeded the standard microbial limit. Klebsiella spp., Staphylococcus spp. and Pseudomonas spp. were encountered in all samples. E. coli, Vibrio spp. and Salmonella spp. were also found in a majority of the samples. Besides, all the isolates were found to be multidrug-resistant. The isolates showed almost 100% resistance against Cefuroxime and Cefixime. A higher proportion of resistance was also reported against Vancomycin and Azithromycin. Whereas, Gentamycin, Ceftriaxone, Colistin and Levofloxacin sensitivity were found in all the isolates. Such chicken-based frozen snack items contaminated with multi-drug resistant microorganisms could be potential vehicles for transmitting food-borne diseases.

Co-Pathogenesis of Human Herpesvirus with HIV In Africa
Authors: Waliaula Paul
Published: May 2021

Human Herpesviruses (HHV’s) are ubiquitous in human populations globally, and they cause significant morbidity and mortality. HHV’s establish a latent infection that is accompanied by periodic virus reactivation as a result of HIV infections. Further, HIV/AIDS infection in sub-Saharan Africa is perceived to be a significant health concern as it accounts for up to 70% of infectious diseases in the region. Until now, the role played by HHVs is increasingly being recognized. The co-infection of HIV with HHV’s changes severity or the natural course of HIV infection which defines the AIDS conditions in HIV infected individuals. Presently, treatment of HIV/AIDS by antiviral drugs targets the clinical manifestations of both HIV and HHVs at their productive stage and boost the immunity of HIV infected individuals, but they are ineffective at eliminating these viruses (HHVs and HIV) from the infected persons. This review focuses on outlining the epidemiology, distribution and role played by HHV’s in the pathogenesis of HIV infection in African countries. Additionally, this information is significant in crystallizing and providing an update on recent advancements on HHV’s and HIV infections in Africa and possible future directions in this field of research.

Published: May 2021

Nile tilapia Oreochromis niloticus (L.) is a recent re-introduction in Lake Naivasha and is one of the fish species that has crossed into Lake Oloidien. This study assessed and compared the population characteristic of O. niloticus under different physicochemical conditions of water in L. Naivasha (main) and L. Oloidien. Samples of water for selected water quality parameters and fisheries data from catch survey were collected between 2017 and 2018. Results indicate the highest conductivity levels recorded in 2018 as 2916 ±11.30 μScm-1 and 282.33 ± 4.33 μScm-1 for L. Oloidien and L. Naivasha respectively. Mean total lengths of O. niloticus were 19.1± 1.8 cm and 23.6 ± 2.9 cm for L. Oloidien and L. Naivasha respectively. Mean weight of O. niloticus was 129.3 ± 37.8 g in L. Oloidien and 260.9 ± 81.0 g in L. Naivasha. Length-weight relationship analysis showed a negative allometric growth (b = 2.526) and (b = 2.983; p > 0.05) in lakes Oloidien and Naivasha respectively. The relative condition factor (Kn) values were slightly lower in O. niloticus from L. Oloidien compared to the main Lake. Differences between the two lakes in the population characteristics of O. niloticus may be attributed to the observed differences in the habitat conditions, including the conductivity and pH levels.

Published: May 2021

Coptodon zilli and Micropterus salmoides were introduced into Lake Naivasha in 1929 and 1959, to boost the fisheries and for recreational fishing respectively. The population of the two fish species in the lake has been declining making it necessary to assess selected growth aspects to inform management and policy making for recovery and establishment of their populations. Length-weight relationship, condition factor, sex ratio and length at first maturity of the fish were studied from October 2016 to November 2018. A total of 303 fish samples; 193 C. zilli and 110 M. salmoides were studied. Results showed that C. zilli and M. salmoides had an allometry coefficient value of 2.9 and 3.1 and condition factor (K) value of 1.77 and 1.39 respectively. The sex ratios (male: female) of C. zilli and M. salmoides were 1.1:1 and 1.3: 1 respectively. The shortest total length for mature C. zilli and M. salmoides recorded were 12 cm and 26.5 cm while 21.8 cm and 51 cm were for the longest respectively. The fish exhibited allometric growth pattern. They were also found to be in good condition with K factor above 1. It was concluded that the fish are generally in a good condition though the early maturity for C. zilli could be a sign of either environmental or fishing pressure. Domination of the species by males is a case for concern since it presents uncertainty on the future of the fisheries. Restocking of Lake Naivasha with the two fish species should be considered.

Published: May 2021

This study focused on the modelling and experimental investigation of Copper-Zinc alloy using Split-split plot design. The effects of process parameters such as percentage by volume of material, material type (copper and zinc), pressure and their interactions on the mechanical properties of the produced copper-zinc alloy using split-split plot design was investigated. The mechanical properties examined in this study include; tensile strength, modulus of elasticity, shear modulus and hardness. The values obtained from the evaluation of these mechanical properties were imputed into the analytical design of the split-split plot to obtain its numerical designs. Interactive model for the process parameters were also developed for this study. The sum of squares (SS) and the mean of square (MS) were calculated from the numerical designs of split-split plot to obtain the Fisher’s ratio (F_cal) values. The results of the calculated Fisher’s ratio at significant value of 0.05 for the process parameters and their interactions ranges from -57.70 to 8.50, and were presented on analysis of variance (ANOVA) table. The results obtained shows that there is strong interraction between pressure, percentage by volume of zinc and copper in the production zinc-copper alloy in alloy manufacturing industries.

Home Automation Using IOT
Authors: Kasbekar Meena , Khan Nida , Kadam Atharva , Gajare Prof. Milind
Published: May 2021

In this era of digitization and automation, the life of human beings is getting simpler as almost everything is automatic, replacing the old manual systems. Nowadays humans have made internet an integral part of their everyday life without which they are helpless. Internet of things (IoT) provides a platform that allows devices to connect, sense and control remotely across a network infrastructure. In this paper we focus on home automation using IOT. The IOT devices controls and monitors the electronic, electrical and the mechanical systems used in various types of buildings. The devices connected to the cloud server are controlled by a single admin which facilitate a number of users to which a number of sensor and control nodes are connected. The admin can access and control all the nodes connected to each user but a single user can control only the nodes to which the user itself is connected. This whole system using Internet of Things (iot) will allow mobile devices and computers to remotely control all the functions and features of home appliances from anywhere around the world using the internet connection. The system designed is economical and can be expanded as it allows connection and controlling of a number of different devices. Advancement in technology has not only transformed our life but also extended in every sphere of our way of living. Most of the electronic devices are manually monitored on regular basis to ensure the optimal operation. To install new application specific devices not only increases the cost but also replaces the old device. Here we propose a system, which can monitor and schedule any old electronic device through a mobile application and its operation can be optimized by saving time and energy.

Published: May 2021

Introduction

The aim of our study was to analyze the regional differences in diabetic retinopathy (DR) prevalence and its co-existing social and demographic factors in the overall population of Poland in the year 2017.

Material and methods

Data from all levels of healthcare services at public and private institutions recorded in the National Health Fund database were evaluated. International Classification of Diseases codes were used to identify patients with type 1 and type 2 diabetes mellitus (DM) and with DR. Moran's I statistics and Spatial Autoregressive (SAR) model allowed to understand the distribution of DR prevalence, and its possible association with environmental and demographic exposures..

Results

In total, 310,815 individuals with diabetic retinopathy (DR) were diagnosed in the year 2017 in Poland. Of them, 174,384 (56.11%) were women; 221,144 (71.15%) lived in urban areas; 40,231 (12.94%) and 270,584 (87.06%) had type 1 and type 2 DM, respectively. The analysis of the SAR model showed a higher level of average income and a higher number of ophthalmologic consultations per 10 000 adults in the particular county were the significant factors for the occurrence of DR in the counties.

Conclusions

The analyses of social, demographic, and systemic factors co-existing with DR revealed that the level of income and the access to the ophthalmologic and diabetic service are crucial in DR prevalence in Poland.
Gentiana macrophylla exhibits a potential therapeutic effect on osteoarthritis (OA) via modulating disease-related proteins
Authors: Xu Haitao , Gao Ningyang , Zheng Yuxin
Published: May 2021

Introduction

Prostaglandin E2 (PGE2) has been reported to cause cartilage degradation in the pathogenesis of osteoarthritis (OA). Matrix metallopeptidases (MMPs) play important roles in the pathogenesis of OA, while p-AKT and p-P39 signaling pathways were reported to be activated in the pathogenesis of OA. In this study, we aimed to investigate the effect of Gentiana macrophylla (GM) on the treatment of OA.

Material and methods

Primary rat chondrocytes were treated with PBS, IL-1β, and IL-1β+GM respectively to established in vitro models, and in vivo models were set up as a SHAM group, a monoiodoacetic acid (MIA) group, a MIA+GM (low dose) group and a MIA+GM (high dose) group.

Results

In primary rat chondrocytes, the IL-1β treatment elevated the expression of PGE2 and COX2 mRNA. However, the GM treatment reduced the expression of PGE2 mRNA and COX2 mRNA. Also, the GM treatment reduced the expression of above MMPs in primary rat chondrocytes treated with IL-1β. Moreover, unlike P38 and AKT, GM treatment could reduce the expression of p-P38 and p-AKT in primary rat chondrocytes treated with IL-1β. Also, GM treatment reduced the up-regulated expression of COX2, MMPs including MMP-1, MMP-3 and MMP-13, and p-P38 and p-AKT in OA rat models, thus exhibiting a therapeutic effect on OA pathology.

Conclusions

Our study demonstrated the inhibitory effect of GM on the up-regulated expression of PGE2, Cyclooxygenase-2 (COX-2), MMPs including MMP-1, MMP-3 and MMP-13, AKT and P38 in OA models, thus verifying the therapeutic effect of GM on the treatment of OA.

Introduction

Cardiac rehabilitation is a component of heart failure (HF) management, but its effect on ventricular arrhythmias is not well understood. We analyzed the antiarrhythmic effect of a 9-week hybrid comprehensive telerehabilitation (HCTR) program and its influence on long-term cardiovascular mortality in HF patients taken from the TELEREHabilitation in Heart Failure Patients (TELEREH-HF) trial.

Material and methods

We evaluated the presence of non-sustained ventricular tachycardia (nsVT) and frequent premature ventricular complexes ≥ 10 beats/hour (PVCs ≥ 10) in 24-hour ECG monitoring at baseline and after 9-week HCTR or usual care (UC) of 773 HF patients (NYHA I-III, LVEF ≤ 40%). Functional response for HCTR was assessed by changes – delta () – in peak oxygen consumption (pVO2) as a result of comparing pVO2 from the beginning and the end of the program.

Results

Among 143 patients with nsVT, arrhythmia subsided in 30.8% after HCTR. Similarly, among 165 patients randomized to UC who had nsVT 34.5% did not show it after 9 weeks (p = 0.481). There was no significant difference in the decrease in PVC ≥ 10 over 9 weeks between randomization arms (14.9% vs. 17.8%, respectively p = 0.410). Functional response for HCTR in ΔpVO2 > 2.0 ml/kg/min did not affect occurrence of arrhythmias. Multivariable analysis did not identify HCTR as an independent factor determining improvement of nsVT or PVCs ≥ 10. However, only in the HCTR group, the achievement of the antiarrhythmic effect significantly reduced the cardiovascular mortality in 2-year follow-up (p < 0.001).

Conclusions

Significant improvement in physical capacity after 9 weeks of HCTR did not correlate with the antiarrhythmic effect in terms of incidence of nsVT or PVCs ≥ 10. An antiarrhythmic effect after the 9-week HCTR affected long-term cardiovascular mortality in HF patients.

The study analyzed the coronary blood of level of CD31+EMPs, TF protein and IL-33 protein in Acute Myocardial Infarction (AMI) and stable coronary artery disease (SCAD) patients. Human coronary artery endothelial cells (HCAECs) were treated with IL-33 to obtain EMPs. The TF activity of EMPs was tested by Thermo Fisher by adding the TF antibody. Furthermore, TF and Tissue Factor Pathway Inhibitor (TFPI) protein were tested by ELISA. Finally, NF-κB inhibitor dimethyl fumarate (DMF) and soluble extracellular domain of ST2 coupled to the Fc fragment of human IgG1 (sST2) were added to HCAECs which were treated with IL-33, and the TF protein level was also tested by ELISA.

Results

The AMI patients had higher level of CD31+EMPs, TF protein and IL-33 protein than the SCAD patients in coronary artery. In AMI patients (N=27), the IL-33 protein positively correlated with CD31+EMPs (r=0.794, p<0.01). According to the ROC curve analysis, the AUC of CD31+EMPs, TF protein and IL-33 protein were 0.888, 0.962 and 0.778 respectively. In the cell culture, the TF activity and TF protein in EMPs increased gradually with time of intervention by the treatment of IL-33. IL-33 binding to the ST2 receptor promoted TF expression by regulating NF-κB activation in EMPs of HCAECs.

Conclusions

Activated endothelial cells and EMPs they released simultaneously express TF, which is a risk factor for cardiovascular disease.

Dental implants are considered the first choice to replace lost or non-restorable teeth. However, the posterior maxilla remains a challenge in its management because of the quality of bone in the posterior maxilla. Osseo densification (OD) concept has been proposed in the literature to improve primary implant stability, which is an important aspect of osseointegration. Densah bur is novel drills specially designed to enhance a bone density by Osseo densification, which in turn increases primary stability. This present study was conducted to assess crestal sinus floor elevation by osteotome in comparison to Densah bur in the posterior atrophic maxilla. This was a randomized controlled clinical trial conducted on 20 patients to evaluate available crestal bone height loss, implant stability after implant placement in healed posterior maxillary alveolar ridge, whole bone height, Schneiderian membrane trauma, and post-operative complication.

The current study was designed to evaluate the effect of using prophylactic antibiotic in preventing wound infection post operatively in patients with non recurrent hernia surgery. A prospective study of 180 patients with inguinal hernia where divided into three groups -:first group of 90 patients were operated on with administration of three dose of ( third generation) cephalosporin. First dose given perioperatively Second dose given eight hours post operatively later. Third dose given 24 hour post operatively later , Second group 40 patients local Garamycine 80 MG diluted in 250 saline solution was used to wash the wound of each patients , third group fifty patients (27.7%) patients were remain without any antibiotic post operatively. Observation of all patients regarding site of surgery were done till ten days after removal of stitches, so Wound swab were taken whenever any signs of infection begin to show on wound and send for culture and drug sensitivity. Result :wound infection was occur 5.5 % (five patients ) out of ninety patients in the first group while it occur in 2.5% (one patients) in the second group and in the third group 6% ( three patients) conclusion :no difference in infection rate weather the patients receive prophylactic antibiotic or not . there is less infection by using local antibiotic in comparison with other two groups but this difference is not statically significant p-value(0.7082).

Background: The physiological consequences of post-operative pain including Stress response to surgery, Respiratory complications, cardiovascular complications, Thromboembolic complications, Gastrointestinal complications, Musculoskeletal complications and Psychological complications, all of which could delay or impair postoperative recovery and increase the economic cost of surgery as a result of the longer period of hospitalization. Inadequate post-operative pain control may also lead to the development of chronic pain after surgery .Aim of This study: is to evaluate the preemptive analgesic effect of intravenous ketamine in laparoscopic cholecystectomy. Patients and Methods: double blinded randomized clinical trial conducted at Al-Yarmouk teaching hospital, over a period of one year from March 2013 to March 2014 on a total of 120 adult patients scheduled for elective laparoscopic cholecystectomy, Patients were divided in to three groups of 40 patients each, the study drug administered intravenously during induction. Groups A and B received ketamine in a dose of 1 and 0.5 mg/kg, respectively, whereas group C received isotonic saline. The degree of pain at rest and deep breathing postoperatively were estimated using VAS, time of first analgesic dose, total opioid consumption, nausea, vomiting and hallucination were recorded for 24 h postoperatively. Results: postoperative pain scores were significantly low in group A when compared with the other groups at most times in the first 24 hours. Highest pain score was in group C at 0 h. Postoperative analgesic consumption was minimum in group A then group B and highest in group C. There was little significant difference in the pain scores between groups B and C. Group A had a significantly higher blood MAP than group B at 0, 0.5 and 1 h. 7.5% incidence of hallucinations were in group A. Conclusion: According to this study we conclude that preemptive ketamine in a dose of 1 mg/kg has a definitive role in reducing postoperative pain and analgesic requirement in patients undergoing laparoscopic cholecystectomy. A low dose of 0.5 mg/kg had little significant in preemptive analgesic effect and in reducing analgesic requirement.

The current study is intended to inspect the potential impact of ethical leadership practices (EL) of intermediate level administration (i.e., faculty deans, department heads) on lecturer job satisfaction (LJS) at a private higher education (HE) institution (UX) in Ho Chi Minh city, Vietnam. A conceptual framework linking EL and LJS was developed grounded on the ethical leadership conceptualizations of Brown et al. (2005), Kalshoven et al. (2011), and Langlois et al. (2014). Accordingly, ethical leadership works as a multidimensional construct encompassing a set of five values or explicit behaviors, i.e., care, critique, integrity, fairness, and ethical guidance. Further, the constructs and effects of EL on LJS are primarily conceptualized in light of Social Exchange Theory and Social Learning Theory. Primary quantitative data was collected through an anonymously self-administered survey of all 378 lecturers permanently employed at eight faculties at UX’s main campus via a non-probability purposive sampling method. The totality of 256 valid questionnaires yielded a response rate of 68% for stepwise data analysis with inferential statistical methods (i.e., internal reliability test, factor scores, correlation, and multiple regression). The regression findings reveal that all five dimensions of EL significantly positively explained the variance in job satisfaction as perceived by UX lecturers (p < .001). These findings suggest both theoretical and practical implications. The present study expands our understanding on ethical leadership by verifying its predictive power on the job satisfaction levels as self-reported by HE lecturers. Therein lies a conclusion that well-established ethical conducts for HE administration may assist them in making key decisions with care, fairness, critique, integrity, and ethical guidance.
