Jobelyn® is a multi-functional natural dietary supplement made from Sorghum bicolour with very high anti-oxidant and anti-inflammatory capacities. The study investigated the role of Jobelyn® in the attenuation of oxido-inflammatory markers induced by tramadol use, abuse and discontinuation over 17 days in rats. The experimental observational study was carried out using male adult albino rats weighing between 100 and 170 g. The experimental design involved five groups. Rats were randomly divided into groups of five, consisting of group 1 (normal control rats), and group 2 (rats treated with tramadol at 40 mg/kg/day) were administered for 10 days and discontinued for seven days. Group 3 administered incremental doses of tramadol from 40 mg/kg/day to 100 mg/kg/day over 10 days and discontinued for seven days. A similar treatment protocol was administered for group 4 and group 5 but were treated with Jobelyn® at a dose of 200 mg/kg/day at the discontinuation phases for seven days. Behavioral assessments (elevated plus maze model of anxiety and open field model of locomotor activity) and biomarkers of oxido-inflammatory stress were assessed. Tramadol-treated groups had significant anxiety responses and locomotory deficits in comparison to the control group. Tramadol-treated groups had significant elevations of nitrites and malondehyde and reduced enzymatic markers such as catalase, glutathione, reduced glutathione, superoxide dismutase, G-s-transferase, glutamic acid decarboxylase and increased activity of acetylcholinesterase when compared to control group. Administration of Jobelyn® attenuated the responses and ameliorated the oxido-inflammatory biomarkers similar to levels in control group. Tramadol induces oxido-inflammatory stress markers in the prefrontal, striatum and hippocampus in rats. Anxiety and locomotory behavioral actions on tramadol treatment were elevated despite discontinuation for seven days. Thus, Jobelyn® at 200 mg/kg/day ameliorated oxido-inflammatory markers induced by tramadol and decreased anxiety responses in albino rats.

Gastrointestinal parasites constitute a serious problem to poultry production in Africa. But often times they are usually ignored by the majority of farmers. Whereas, it is one of the major leading causes of ill-health and high mortality rates in the poultry industry. This study was conducted to determine the prevalence of gastrointestinal parasites of chicken slaughtered at the Jalingo market. A total of 500 gastrointestinal tracts of local chicken comprising of 250 from males and 250 from females were collected from the poultry slaughtering and dressing section of the Jalingo market, and screened for gastrointestinal helminths using the saturated sodium chloride floatation techniques. An overall prevalence of 28.6% (143/500) was recorded with a prevalence of 16.8% (84/500) in males and 11.8% (59/500) females. Nine different species parasites comprising five nematodes and four cestodes, were recorded. Nematodes were the most predominant intestinal parasite with a prevalence rate of 89 (62.2%). And Ascaridia galli 45 (50.5%) was found to be the most prevalent nematode. Other nematodes observed were Capillaria annulata 13.4% (12/89), Heterakis gallinarum 2.2% (2/89), Strongyloides avium 32.5% (29/89), and Syngamus trachea 1.1% (1/89) having the lowest prevalence. Railliatina tetragona 57.4% (31/143) was the most prevalent cestode recorded. Other Cestodes were Hymenolepis carioca 27.7% (15/54), Raillietina cesticellus 12.9% (7/54), and Davainea proglottina 1.8% (1/54). No trematode was recorded in this study. This study showed that nematodes and cestodes were the common helminth parasites in local chicken. There is therefore the need for educating the farmers on the impact of gastrointestinal parasite infection in chicken and the need to institute good management practices so as to reduce their effects on productivity. Sex of the chicken had no statistically significant difference (X2 = 6.12, df = 1; P > 0.05) on the prevalence of helminths.

Background: Acute and chronic heart or kidney failure affect each other in cardiorenal syndromes (CRS). In CRS, hemodynamic and non-hemodynamic changes occur, causing acute or progressive renal and cardiac failures. CRS is classified into five types based on the first organ failure and causes failure of the other organ. We believe that the current CRS classification is not the correct one that effectively describes the underlying cause of CRS. Hence, we consider it better to be classified into three categories (cardiorenal, renocardiac, and cardio-reno-cardiac syndrome) and then subdivided into acute and chronic types or types 1 and 2 (respectively, according to the onset of the underlying type of failure (i.e., acute or chronic). Other subtypes that occur inthe heart and dysfunction occur simultaneously are acute cardio-reno-cardiac syndrome (type 5) and Chronic cardio-reno-cardiac syndrome (type 6). Aim: In Part 1 of the review series, the pathophysiological mechanisms and clinical and therapeutic applications of all types of CRS will be narratively discussed and updated. Furthermore, we provide a comprehensive review of diagnostic biomarkers and their clinical significance in the identification, outcome prediction, and treatment of all CRS types. Method: An extensive search of PubMed, Google, EMBASE, Scopus, and Google Scholar was conducted for review articles, original articles, and commentaries published between Jan 2010 and Aug 2024 using different phrases, texts, and keywords, such as CRS, renocardiac syndrome, and CRS. The topics included secondary CRS, CRS pathogenesis, CRS therapy, SLGT inhibitor use in CRS, novel therapy in CRS types, and prevention of CRSs. Conclusion: Renal and cardiac failure in patients with CRS seem to have different pathophysiological mechanisms. Early detection and treatment can improve the outcomes of CRS. Clinical manifestations and therapy protocols vary according to pathophysiology. Hence, new guidelines and research on universal diagnostic and treatment techniques are urgently required. Moreover, the current nomenclature for CRS is confusing; therefore, we believe that a new nomenclature system should be introduced, reducing confusion and making differentiation between CRS types easier and less confusing.

Tidal and riverine flows are viable energy sources for consistent energy production. Installing and operating marine hydrokinetic (MHK) turbines requires assessing any potential impact of debris accumulation on turbine performance and sediment transport. More specifically, MHK devices may alter the natural sediment transport processes and cause debris accumulation, disrupting the natural sediment dynamic. In turn, these processes could affect the turbine’s performance. We carried out a series of large-eddy simulations coupled with bed morphodynamics, introducing various debris loads lodged on the upstream face of a utility-scale turbine tower. The objective is to systematically investigate the impact of debris accumulation on the performance and hydro-and morpho-dynamics interactions of the horizontal-axis MHK turbine under rigid and mobile bed conditions. To that end, we (1) employed the actuator line and surface methods for modeling turbine blades and the nacelle, respectively,(2) directly resolved individual logs, and (3) solved the Exner equation to obtain the instantaneous bed deformation of the mobile bed. Our analysis revealed that while the spinning rotor amplifies scour around the pile, debris accumulation modifies the sediment dynamics of the system. Also, it found that morphodynamic processes accelerate the wake recovery, slightly enhancing the turbine's performance.

Anemia, iron deficiency and iron deficiency anemia are common blood disorders. The role of vitamin D was agreed to be regulating in calcium and phosphate absorption and bone metabolism and its deficiency is observed as a crucial nutritional problem. Vitamin D is created under the skin by ultraviolet light. It is usually get vitamins from the food; however, in the case of vitamin D, there simply are not enough rich food sources for people to get adequate amounts in their diet. Its effects on the prevention of diseases such as cardiovascular disease and anemia has received much attention recently. To get sufficient vitamin D, need to be exposed to sunshine or use supplements. Vitamin D3 was found in the largest population as a deficiency. With regard to hemoglobin was the subject whom has less normal range of hemoglobin (19.05%) than international normal range, and in ferritin the low population number was the subject whom has less normal range of ferritin than WHO normal range. The population who has low ferritin also has low vitamin D3 and variable hemoglobin. According international guidelines, optimizing nutrition with daily or intermittent (1 to 3 times per week) iron supplementation, should be considered a first-line intervention in high-risk or high-prevalence groups. Although it is probably less effective than daily iron supplementation, intermittent iron appears to be a useful and cost effective way of controlling anemia and iron deficiency anemia. This may indicate that a positive relation between the low concentration parameter of vitamin D3 and ferritin level but no significant correlation with hemoglobin.

Ensuring consistent raw material quality is a significant challenge in chemical manufacturing, particularly for medicinal compounds where safety and efficacy are paramount. In these situations, a unique methodology known as Statistical Process Control (SPC) come into play. This study provides statistical process control analysis of four critical operational parameters for most the raw chemical compounds, especially in the medicinal chemistry— Specific Optical Rotation (SOR), Water Content (WC), RI, and Chromatographic Purity (CP)—derived from a dataset of 26 observations in an applied engineering context. The methodology encompasses descriptive statistics, rigorous distribution identification using Goodness-of-Fit tests, and process stability assessment via Individual- Moving Range (I-MR) and Exponentially Weighted Moving Average (EWMA) control charts. Descriptive statistics revealed diverse data characteristics, notably the high positive skewness (2.623) and kurtosis (9.386) of WC (Mean ± Standard Deviation: 0.177±0.106987) and the presence of negative values for SOR (Mean: -0.1, Min: -2, Max: 2). Distribution fitting identified Logistic and Normal as the most suitable for SOR, while RI demonstrated a best fit for normal distribution with Johnson Transformation. WC and CP exhibited significant non-normality and challenges in fitting standard distributions, often accompanied by warnings regarding convergence or parameter estimation stability. Crucially, control chart analysis identified significant out-of-control conditions for SOR, WC, and RI, indicating inherent process instability. CP, conversely, demonstrated stability with the optimized EWMA chart. The findings underscore the necessity of tailored statistical approaches for diverse data characteristics in quality control. Implementation of Statistical Process Control should not be underestimated in the chemical manufacturing industry, notably in the developing nations.

Transglutaminase 2 (TG2) is an inducible transamidating acyltransferase that catalyzes Ca2+-dependent protein modifications. TG2 enzyme disruption has been implicated in several different disease processes and disorders such as Huntington and Parkinson’s diseases, cancers such as breast, ovarian and pancreatic cancers. Coeliac disease (CD) is the one disease state that TG2 activity plays a crucial role. To date, a gluten-free diet is the only accepted form of therapy for CD. Because of the important role of TG2 enzyme in the initiation of CD, therefore, this study was aimed at the identification of TG2 inhibitors from natural sources, as a potential intervention in CD therapy. Competitive amine inhibitors are the most widely used TG2 inhibitors because they are commercially available, chemically stable and relatively non-toxic in living systems. The natural products chosen for this study were dietary flavonoids. Flavonoids were extracted from different food samples. The flavonoids food extracts were subjected to the TG2 activity assays to examine their effect on the enzyme activity. The assays were carried out under optimal conditions of pH, Ca2+ and with N, N-dimethylcasein (acyl-donor) or casein (acyl-acceptor) as acyl-donor substrates and biotin cadaverine (acyl-acceptor) or TVQQEL as (acyl-donor) substrates. TG activity was measured by two different microplate assays, Biotin-labeled cadaverine incorporation assay and Biotin-labeled peptide cross-linking assay. In the TG2 amine incorporation activity, all of food extracts display a significant inhibition effect towards the human recombinant transglutaminase2 (hrTG2) and guinea pig transglutaminase 2 (gplTG2) (20 - 50% of inhibition). While in the TG2 cross-linking activity, the majority of food extracts displayed an inhibition effect on the gplTG2 cross-linking activity (50 - 70% of inhibition) but only the strawberry and kale extracts showed an effect on hrTG2 activity (40 - 50% of inhibition). The inhibition of TG2 activity can be considered as a potential therapeutic target in the treatment of CD.

The wet coating of anhydrous borax powders with stearic acid (SA) to reverse their inherent hydrophilic surface properties was investigated. The coating procedure was based on the results from a previous study that revealed that the stearic acid solution (2 wt. % SA) mixed for 60 minute at 750 rpm on the magnetic stirrer was sufficient for the surface modification of anhydrous borax. For the experiments, stearic acid powders were first dissolved in water at 80 °C. The mixture obtained by adding anhydrous borax powders to this solution was vigorously mixed on a magnetic stirrer to initiation and completion the surface modification. Each of these solutions was then filtered using a filter paper to separate the undissolved particles, and the residue on paper was dried at 50 °C for 48 h until constant weighing was obtained. Wettability has been accepted as a key parameter for success in wet coating treatment. This parameter gained via the experimental characterization technique was used for an evaluation of the powder properties. The degree of wettability of anhydrous borax powders was measured and compared both after their surfaces were coated with stearic acid and after they were treated with water for a certain period of time in an aqueous environment. The stearic acid coating made the powder hydrophobic and this property was highly preserved after washing.

Brain tumors (BTs) are deadly diseases that can strike people of every age, all over the world. Every year, thousands of people die of brain tumors. Brain-related diagnoses require caution, and even the smallest error in diagnosis can have negative repercussions. Medical errors in brain tumor diagnosis are common and frequently result in higher patient mortality rates. Magnetic resonance imaging (MRI) is widely used for tumor evaluation and detection. However, MRI generates large amounts of data, making manual segmentation difficult and laborious work, limiting the use of accurate measurements in clinical practice. As a result, automated and dependable segmentation methods are required. Automatic segmentation and early detection of brain tumors are difficult tasks in computer vision due to their high spatial and structural variability. Therefore, early diagnosis or detection and treatment are critical. Various traditional Machine learning (ML) techniques have been used to detect various types of brain tumors. The main issue with these models is that the features were manually extracted. To address the aforementioned insightful issues, this paper presents a hybrid deep transfer learning (GN-AlexNet) model of BT tri-classification (pituitary, meningioma, and glioma). The proposed model combines GoogleNet architecture with the AlexNet model by removing the five layers of GoogleNet and adding ten layers of the AlexNet model, which extracts features and classifies them automatically. On the same CE-MRI dataset, the proposed model was compared to transfer learning techniques (VGG-16, AlexNet, SqeezNet, ResNet, and MobileNet-V2) and ML/DL. The proposed model outperformed the current methods in terms of accuracy and sensitivity (accuracy of 99.51% and sensitivity of 98.90%).
