Gestational diabetes mellitus (GDM) is associated with an increased maternal and fetal risk of complications. Other than lifestyle modifications and diet, little prevention can be done towards this maternal complication. Through a preclinical approach and a retrospective clinical trial, we investigated the effects of maternal supplementation with a nutraceutical composition based on resveratrol (RSV) and alpha-lipoic acid (ALA) on insulin resistance and GDM status

Background to Study: Lead (Pb) is ubiquitous in the environment and toxic. It has many negative effects on many organs and induces biochemical, physiological, and behavioural alterations on the brain. Monodora myristica is a calabash nutmeg belonging to the family of Annonaceae.It is a rich source of flavonoids which have been shown to exhibit both antioxi-dant and anti-inflammatory properties. We evaluated the protective role of Monodora myristica on lead-induced toxicity in D. melanogaster in this study

The use of surface electromyography (sEMG) signals for clinical diagnosis is well appreciated in the medical field. However, the use of sEMG signals for the control of powered prosthetic limbs is still regarded as a futuristic idea. Past and present studies have focused more on the upper limb (hand) as compared to the lower limb (leg). The challenges associated with the controlling leg movement include designing for both balance and locomotion. After amputation, the muscle orientation and alignments on the residual stump changes as some of the anatomical landmarks are changed during surgical procedure. To achieve locomotion, some amputees, generally from third-world nations, use passive mechanical prosthetic limbs with a fixed ankle.

In the past few years, E-cigarettes (or vaping) are getting the popularity among the youth in Bangladesh. This is critical as it may lead to an increase in the number of smokers in future. The study aimed to identify the trend of E-cigarette smoking, habitual pattern of E-cigarette smokers, and their perception and experiences of health hazards. A cross-sectional mixed methods study was conducted from April to November 2020 in Dhaka and Chittagong cities. A total of 370 E-cigarette smoker aged 18 and above years, were surveyed face-to-face using a semi-structured questionnaire

Maize is the most important crop in Kenya and parts of Sub-Saharan Africa. However, yields are below potential due to abiotic and biotic constraints. One of the major biotic concerns is maize lethal necrosis disease (MLN), which causes up to 100% yield losses. MLN is caused by the synergistic infection of two viruses, Maize chlorotic mottle virus (MCMV) and a potyvirus, commonly Sugarcane mosaic virus (SCMV)

Candida albicans is an opportunistic agent that can produce systemic infections in immunosuppressed patients. By varying its cell wall antigens this fungus can evade the immunological response by varying its cell wall antigens. On the other hand, Larrea divaricata Cav. (Jarilla) is a widely spread plant in America and it is used in folk medicine to treat several pathologies. It has been shown that antibodies against Jarilla proteins of crude extract (JPCE) cross-react with proteins of other microorganisms such as Gram-negative bacteria.

The objective of this study was to evaluate the bond strength of fiberglass posts (Reforpost ®) cemented with RelyX U200 and RelyX Luting 2, with (A) and without (WA) ultrasonic activation in the root canal of bovine teeth. The penetration of the cements into dentine tubules was also assessed. Methods: Forty bovine incisors were selected and endodontically treated, and then divided into 4 groups (n = 10). Fiberglass posts were cemented with RelyX U200 and RelyX Luting 2 and activated with an ITSMO ultrasound insert in 2 groups; the other two groups received no ultrasonic activation. After 24 hours of cementation, the roots were sectioned into slices of approximately 1 mm each. Confocal microscopy and push-out test were performed, and all specimens were subjected to 200× magnification optical microscopy for mode of failure evaluation. Statistical analysis was done with three-way ANOVA, followed by the Fisher’s test (α = 0.05)

Dental dyschromias have several origins among them we cite fluorosis. Dental fluorosis is defined as a qualitative anomaly of the enamel, resulting histologically in hypomineralisation due to excessive ingestion of fluorides during amelogenesis. Clinically, it takes the form of opacities in the enamel. These opacities may affect homologous teeth symmetrically, and generally affect several groups of teeth. Topographically, isolated or confluent white lines or discrete white patches are observed. Interpretismatic spaces are wider, resulting in porous and permeable enamel. On the one hand, this explains the post-eruptive dyschromias, where exogenous pigments penetrate the pores and transform the white opacities into brown. It is classified into 3 categories: mild, moderate and severe. So that this case was moderate fluorosis and appropriated for the treatment with enamel microabrasion. Differential diagnosis for this condition includes: enamel hypoplasia, amoelogenesis imperfecta, and dental caries.

In doped calcium fluoride transparent conducting powder were prepared by solid-state reaction method. Structural properties of the samples were investigated as a function of various In-doping levels (x=0.00-0.01-0.02-0.03). The results of x-ray diffraction have shown that the samples are polycrystalline structure in cubic phase and show presence (111), (220), (311), (400) planes in pure CaF2 sample and the preferred orientation is (220) for pure CaF2 and we have peaks correspond (101), (112), (200), (202) for In for all samples and the preferred orientation is (112) for In for all samples. The average of crystallite size is within the range [2.976-0.845nm] for all samples. The relative intensities, distance between crystalline planes (d), crystallite size (D) and lattice parameters (a) were determined. Measuring the infrared spectrum of pure Calcium fluoride, it is found that there are six vibratory frequencies, namely: (3444.52 - 1517.59 - 1138.40 - 876.40 - 639.93 - 436.29) cm- 1 and six vibratory frequencies for indium doped calcium fluoride at 3wt%. (3441.94 - 1516.77 - 1138.44 - 876.55 - 642.09 -436.44) cm- 1 The study showed that the absorbance values, the absorption coefficient, the refractive index and the optical length were in the indium doped sample by 3wt% greater than that of the pure Calcium fluoride compound and are respectively: α=14.163 cm-1 n=1.767.

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

In this paper, we report on the synthesis of BaTiO3 nanowires via the anodic aluminum oxide template method. To fill in the precursors of BaTiO3 into anodic aluminum oxide templates, the vacuum and drop loading method developed in our previous study was used. Ba(CH3COO)2 (barium acetate) and C12H28O4Ti (tetraisopropyl orthotitanate) were used as Ba and Ti sources, respectively. Anodic aluminum oxide membranes with the through-hole diameter of ~200 nm were used as the template for BaTiO3 nanowires.
