The Objectives of the Study: To evaluate the Antinutritional components, Amino acid profiles and the physic-chemical properties of Hura crepitan (Sand box) seed.
Design of the Study: This study was structured to fit into using a combination of T-test and one way Analysis of Variance (ANOVA) to evaluate the data obtained from the laboratory analysis.
Place and Duration of Study: This research work was done at the Department of Food Science and Technology Laboratory, Federal University of Technology, Owerri, Nigeria, between May 2019 and November 2019.
Methods: The mature dry fruits of the Hura crepitan seeds were harvested from the plants on Federal University of Technology Owerri, Imo State campus.
The Hura crepitan seeds were sorted in order to remove dirts and foreign other foreign contaminants. The cleaned seeds were divided into four portions and stored in separate glass containers for further processing. The first portion of the seeds were dried at 60°C in Gallen Kamp moisture extraction oven for 6 hours at and pulverised in a Monilex blended into flour, some seeds were boiled while some portions were roasted and processed into fine flour and subsequently subjected to analysis to evaluate the antinutritional contents, amino acid s as well as determining the physic-chemical properties of the samples.
Results: The results obtained suggested that the anti-nutrients in the raw seed-flour were flavonoids with 17.50%, alkaloid (6.20%), tannin (5.24%), and cyanogenic glycoside (1.76%). Fermentation and moist cooking were found to be more effective in the reduction of the anti-nutrients in the Hura crepitan seeds. The amino acid profiles were evaluated, and twenty amino acids were identified in the seed flour. The three major ones implicated were arginine (3.25 g/100 g in cooked and 8.05 g/100 g in fermented), glutamic acid (6.05 g/100 g in cooked and 10.2 g/100 g in fermented) and valine (8.03 g/100 g in raw and 8.58 g/100 g in fermented). The limiting amino acid is methionine with a chemical score of 44.52%. the physicochemical properties of the sandbox seeds evaluated suggested that the free fatty acids values ranged from 3.60% to 6.03% and there were no significant differences (P>0.05) among the samples, the iodine value ranged from 104.94% to 126.90%, the peroxide value for the sample varies between 2.96% to 44.81%.
Conclusion: This study suggested that the Hura crepitan seed contains appreciable amounts of essential amino acids as well as having good physicochemical properties while the use of moist heat and/or fermentation can reduce the antinutritional components to the bearest minimum. Hence, can be utilized some areas of food industries where protein (amino acids) are critically required.

Introduction: Honey is thought to preserve the cells by preventing autolysis and putrefaction. Thus, studies have shown that honey has a good preventive putrefactive property mainly because honey contains seven tetracycline derivatives, fatty acids, lipids, amylases and ascorbic acid and hydrogen peroxide. Therefore, honey is used as an agent for preventing autolysis and putrefaction.
Aim: This research aims to investigate the efficacy of some concentrations of the honey solution in fixation of some tissues (Such as kidney, liver, heart, lungs and muscle).
Methodology: A Wistar rat was sacrificed by vertical abdominal incision and the above-mentioned organs ware fixed in 10% formalin (positive control), 10% honey and 20% honey this grouped the research specimen into 3 groups. Histological examinations of these organs were carried out.
Results: Almost all the histological sections fixed in honey solution revealed normal nuclear as well as a cytoplasmic outline as compared with formalin-fixed organs, except for muscle which shown some level of swollen and fragmenting tissue.

Published: July 2020

Corona virus COVID-19 is a pandemic whose devastating effects were felt in all corners of the world and by all humanity of whatever age, gender, economic and social status from the beginning of January 2020 and the intensity increasing day-by-day. The patients that had symptoms were isolated while waiting for results. In some countries, self-isolation was encouraged while in others, people had to be put in quarantine facilities to cut down the spread chain immediately. Different countries identified quarantine centers where individuals were quarantined for 14 days upon which they would be tested. A philanthropist Bill gates, the Microsoft billionaire, committed himself to donating resources for developing a vaccine. Research centers directed their focus to establishing a cure or a vaccine for the killer virus. After four months of trials and tests, there was no sign of a cure. Many governments in the world applied a partial or full lockdown guided by the rate of infection and death. China was the first to call for a complete lockdown as it struggled with the new pandemic. The CoVID 19 pandemic has affected every facet of life; social, economic and mental. This has placed a lot of strain on governments and individuals. The economic status of many countries and individuals has been adversely affected and may take a long time before recovery.

Published: July 2020

Aim: To determine spectrum of bacteria infecting burn wound and its antibiotic susceptibility at Benue State University Teaching Hospital (BSUTH).
Study Design: A one year prospective study of the microbial profile in burn wound infection at BSUTH, Makurdi.
Methodology: All patients admitted from August 2018 to July 2019 with burn wound who had wound swab microscopy culture and sensitivity (MCS) after thorough cleaning of the wound were included in the study. Data collected included the Age, Sex, Occupation, Total Body Surface Area (TBSA) of burn, injuring agent, type of burn, bacteria cultured from the wound, antibiotic susceptibility, number of days of admission and outcome of treatment.
Results: Out of the 63 patients admitted, flame was the predominant injuring agent seen in 54 (85.7%) patients. The age group 21 – 30 years was the most affected, 27 constituting 42.9%. Burn wound infection occurred in 25(39.7%) patients from whom 33 bacterial isolates were recovered. Gram negative organisms Pseudomonas species and Proteus species were the commonest bacteria isolated constituting 21.21% each. Other isolates were Staphylococcus aurous 36.36%, Escherichia coli 15.15%, Klebsiella species and Staphylococcus saprophyticus (each 3.03%,). There was multiple bacteria colonization of wounds and antibiotics resistance. There was no gender difference in the burn wound infection, P =0.7819.
Conclusion: The sensitivity pattern showed many of the bacteria to be resistant to commonly administered antibiotics but sensitivity patterns got are important for empirical antibiotics prescription when patients come with glaring sepsis and are waiting for wound swab microscopy culture and sensitivity. Studying the microbial profile with antibiotic resistance pattern in burn’s wound infection should be a continuous process in all burn units/departments. This will help to formulate and modify at regular intervals, a hospital/departmental antibiotic policy according to the present microbial pattern in the respective burns unit.
Perceived Morbidity Patterns among Workers in the Oil Industry of Nigeria
Authors: Osakwe Kennedy A. 
Published: July 2020

Background: Globally, the oil industry is replete with several high-risk activities as seen in seismic exploration, construction, drilling, production, and maintenance. Generated hazards could impact exposed workers. Exposure to associated hazards and rigour of activities usually puts workers in oil and gas installations at risk of developing several occupational illnesses. Environmental problems have also been reportedly associated with these activities as well. This study was thus aimed at determining the perceived environmental effects and morbidity patterns among staff of an oil and gas installation in the Niger Delta Region of Nigeria.
Methods: A descriptive, cross-sectional study design was used in conducting this study in an onshore oil and gas hub in Nigeria. Study group comprised engineers and technicians of various oil and gas specialties. A random sampling method was used to select 256 personnel from the study population. A self-administered questionnaire was administered to the personnel of the facility. Data was analysed using the Statistical Package for Scientific Solutions (SPSS) version 17.0 (statistical software package) for analyses. Ethical considerations were adhered to during this study.
Results: Common complaints include transient tinnitus (97.3%), joint pain of varying degrees (83.6%), occasional prickling sensation in the skin (78.1%) and the lowest frequency of health effects was claims of stressful feeling (56.6%). Environmental problems including the destruction of aquatic biodiversity as well as water contamination were reported in this study.
Conclusion: This study found experience of several morbidities by the respondents. They also reported observation of certain environmental problems related with oil exploratory activities at the oil and gas installation. It is recommended that a regular review of measures be put in place to prevent these health and environmental problems from occurring in or around oil and gas installation located in Nigeria.

AbstractStanding Lamb waves in vibrating plates enable haptic interfaces. If the out‐of‐plane displacement of these waves exceeds 1 µm at frequencies above 25 kHz, a silent friction modulation can be created between a human finger and a vibrating plate. A fully transparent friction‐modulation haptic device based on a piezoelectric thin film is demonstrated. The antisymmetric Lamb mode induced at 73 kHz allows for a functional performance that fulfills all conditions for practical use. Out‐of‐plane displacement reaches 2.9 µm when 150 V unipolar voltage is applied. The average transmittance of the whole transducer reaches 75%. The key points of this technology are: 1) a thin HfO2 layer between lead zirconate titanate film and substrate that prevents chemical reaction between them; 2) the efficient integration of transparent indium tin oxide electrodes and solution‐derived piezoelectric lead zirconate titanate thin film onto optical‐grade fused silica; and 3) the use of a transparent insulating layer made of SU‐8 photoresist.

AbstractOwing to the difficulty in acquiring compounds with combined high energy bandgaps and lower‐lying intramolecular charge‐transfer excited states, the development of ultraviolet (UV) thermally activated delayed fluorescence (TADF) materials is quite challenging. Herein, through interlocking of the diphenylsulfone (PS) acceptor unit of a reported deep‐blue TADF emitter (CZ‐PS) by a dimethylmethylene bridge, CZ‐MPS, a UV‐emissive TADF compound bearing a shallower LUMO energy level and a more rigid structure than those of CZ‐PS is achieved. This represents the first example of a UV‐emissive TADF compound. Organic light‐emitting diode (OLED) using CZ‐MPS as the guest material can emit efficient UV light with emission maximum of 389 nm and maximum total external quantum efficiency (EQEmax) of 9.3%. Note that this EQEmax value is twice as high as the current record EQEmax (4.6%) for UV‐OLEDs. This finding may shed light on the molecular design strategy for high‐performance UV‐OLED materials.

AbstractA transparent and stretchable strain sensor based on Ag nanowires (NWs) and poly(3,4‐ethylenedioxythiophene):poly(styrene‐sulfonate) (PEDOT:PSS) patterned microstructure is presented. The regular patterns are achieved by a facile replication and transfer process from near‐field electrospun polyacrylonitrile (PAN) grids on the surfaces of polydimethylsiloxane (PDMS) substrates. Owing to the combined advantages for the unique microstructure of sensor, strong adhesion of polymer PEDOT:PSS to underlying layer, and outstanding conductivity of long Ag NWs, the transparent strain sensor possesses the excellent aspects of high sensitivity (gauge factor = 10.2), wide sensing range (0–100%), long‐term reliability for at least 2000 cycles, and distinct temperature responses. Moreover, the patterned strain sensor can be mounted on different body parts to detect a wide range of human movements and temperature responses in real time, providing multifunctional applications in human/machine interaction, electronic skins, and wearable devices.

AbstractRelapse after allogeneic hematopoietic stem‐cell transplantation (AHSCT) is associated with very poor outcomes. A second transplant offers the possibility of long‐term disease control. We analyzed outcomes with haploidentical donors for second allograft at our institution. All consecutive patients with hematological malignancies (N = 29) who relapsed after AHSCT and underwent a haploidentical transplant (haploSCT) as second transplant between February 2009 and October 2018 were included. Median age was 36 years (interquartile range (IQR) 24‐60); 83% of patients had high/very high disease risk index; 61% of AML/MDS patients had high‐risk cytogenetics; and only 24% were in complete remission at transplant. With a median follow‐up of 46.9 months, the 3‐year relapse, non‐relapse mortality (NRM), progression‐free survival (PFS) and overall survival (OS) were 30%, 39%, 31% and 40%, respectively. In multivariable analysis (MVA), comorbidity index (HCT‐CI) and detectable donor‐specific anti‐HLA antibodies (DSA) prior to second transplant were significantly associated with worse outcomes. Patients with HCT‐CI <3 and without DSA had 3‐year PFS and OS of 53% and 60.3%, respectively. Our findings suggest that haploSCT as second AHSCT is feasible and potentially curative. Lower HCT‐CI and no DSA were associated with lower NRM and improved survival. Haploidentical grafts might be a preferred donor source for second AHSCT as these are high‐risk patients who frequently need to proceed urgently to transplant.

AbstractCapuchins, like other primates, use feedback from sensory cues and digestion to make decisions about which foods to consume and which to avoid. However, little is known about how capuchins make consumption decisions when simultaneously presented with novel and familiar foods, or how food familiarity and macronutrient concentration together influence food choice, topics with potential implications for developmental and health research. In this study, we evaluated the role of familiarity, as well as fat and sugar concentration, in the food selections of captive tufted capuchins (Sapajus apella). In the first experiment, over 10 sessions, subjects were assigned to either a group that chose between one familiar and one novel food item both high in fat or sugar (high condition), or to a group that chose between one familiar and one novel food item both low in fat or sugar (low condition). In the second experiment, subjects were divided into three groups, familiarized with food over five feeding sessions, and then offered the familiarized food and a novel food that varied in fat or sugar for 10 sessions. When offered foods high in fat, capuchins showed no clear signs of neophobia, forming an initial preference for the novel food, rejecting foods less frequently, and selecting foods faster than when offered foods low in fat. These trends were generally not observed in response to foods with sugar. When presented with options that varied in macronutrient concentration, subjects showed an initial interest in the novel food irrespective of whether it was high in fat or sugar, yet formed a final preference for the higher‐concentration item. Findings suggest that the concentration of fat or sugar in novel foods may be an important mediator of exploratory behavior and that capuchins rely on immediate feedback from taste and other sensory cues to make consumption decisions.

Published: July 2020

AbstractAn efficient copper‐catalyzed regioselective C−H alkenylation and borylative alkylation of quinoline N‐oxides with vinyl arenes in the presence of pinacol diborane has been developed. The reaction proceeds through the borylcupration of the vinyl arenes followed by nucleophilic attack of the resulting alkyl copper species to the quinoline N‐oxides. Benzoquinone and KOtBu were identified as the necessary additives at the second step of the reaction that are crucial for the success of the reaction. A wide range of C2‐functionalizaed quinolines were obtained with good functional group tolerance, which may find utilities in pharmaceuticals and synthetic chemistry.

Published: July 2020

AbstractTricyclic ring systems possessing a dibenzo structure joined to a seven‐membered heterocyclic ring frequently show important biological activities. However, a modular approach to these molecules based on efficient intermolecular reaction of readily available chemicals is lacking. Herein, an unprecedented palladium‐catalyzed formal [4+3] annulation for modular construction of these tricyclic systems is described. This reaction features easily accessible reactants (o‐haloarylaldehydes and N‐tosylhydrazones), broad substrate scope, and excellent functional group compatibility. The synthetic potential is demonstrated by the easy scale‐up reactions, late‐stage modification of complex molecules, and collective synthesis of bioactive molecules and approved drugs.
