Sorghum: Nutritional Factors,Bioactive Compounds,Pharmaceutical and Application in Food Systems: A Review

After wheat, rice, maize, and barley, sorghum is the fifth most widely grown cereal on the planet. Due to its highproduction, drought resistance, and heat tolerance, this crop is replacing maize in some areas. Sorghum is available in a variety of colors, including cream, lemon-yellow, red, and even black. The principal grain anatomicalcomponents are pericarp, germ or embryo and endosperm. This review provides an overview of key sorghumgrain components, including starches, fiber, proteins, lipids, and vitamins. Also, we summarized phenolic compounds, flavonoids, tannins, carotenoids, vitamin E, amines, Policosanols and Phytosterols in sorghum grains.Sorghum is used to manufacture bread and porridge, and it provides a significant source of energy and nutritionfor humans; sorghum is extensively farmed for animal feed. However, because the natural components in sorghum are useful in the development of healthy and functional foods, sorghum farming for both biofuel production and human consumption is gaining popularity. Pigmented sorghum grain is high in antioxidants such aspolyphenols, primarily tannins, which have a variety of health benefits, including antiproliferative propertieslinked to the prevention of certain cancers, antioxidant activities linked to the prevention of diseases linked tooxidative stress, and anti-inflammatory effects, as well as improving glucose metabolism. Because these chemicalscannot be assimilated, their application in the food business has been limited, as sorghum is regarded as a lownutritional grain due to the presence of anti-nutritional components such as strong tannins, which form complexes with proteins and iron, limiting their digestibility. This review aims to show the utilization of sorghumas a source of bioactive chemicals and the value they bestow on human health due to the general biological potential it possesses.     

Modulation of prefrontal cortex with anodal tDCS prevents post-exercise facilitation interference during dual task

In this study we aimed to investigate whether transcranial direct current stimulation (tDCS) over the left dorsolateral prefrontal cortex (DLPFC) reduces interference effects of a dual task (DT) on post-exercise facilitation (PEF) of the motor evoked potentials. Anodal tDCS reversed the DT interference on PEF after a non-fatiguing isometric contraction. We conclude that anodal DLPFC tDCS improves the ability to allocate attentional resources and modulates plastic adaptations across brain systems.     

Purification and biochemical characterization of cytosolic glutathione-S-transferase from filarial worms Setaria cervi

The present study reports the purification and characterization of GST from cytosolic fraction of Setaria cervi. GST activity was determined in various subcellular fractions of bovine filarial worms S. cervi (Bubalus bubalis Linn.) and was found to be localized mainly in the cytosolic and microsomal fractions. The soluble enzyme from S. cervi was purified to homogeneity using a combination of salt precipitation, centrifugation, cation exchange and GSH-Sepharose affinity chromatography followed by ultrafiltration. SDS-PAGE analysis revealed a single band and activity staining was also detected on PAGE gels. Gel filtration and MALDI-TOF studies revealed that the native enzyme is a homodimer with a subunit molecular mass of 24.6 kDa. Comparison of kinetic properties of the parasitic and mammalian enzymes revealed significant differences between them. The substrate specificity and inhibitor profile of cytosolic GST from S. cervi appeared to be different from GST from mammalian sources.     

Synthesis of chiral pyrazolo[4,3-e][1,2,4]triazine sulfonamides with tyrosinase and urease inhibitory activity

A new series of sulfonamide derivatives of pyrazolo[4,3-e][1,2,4]triazine with chiral amino group has been synthesized and characterized. The compounds were tested for their tyrosinase and urease inhibitory activity. Evaluation of prepared derivatives demonstrated that compounds (8b) and (8j) are most potent mushroom tyrosinase inhibitors whereas all of the obtained compounds showed higher urease inhibitory activity than the standard thiourea. The compounds (8a), (8f) and (8i) exhibited excellent enzyme inhibitory activity with IC₅₀ 0.037, 0.044 and 0.042?μM, respectively, while IC₅₀ of thiourea is 20.9?μM.     

Prevalence and Associated Factors for Dual Form of Malnutrition in Mother-Child Pairs at the Same Household in the Gaza Strip-Palestine

Background

In many developing countries nutritional, and epidemiological transitions are emerging into continuing undernutrition and escalating overnutrition, giving rise to the double burden of the malnutrition phenomenon.

Objectives

This study aims to determine the prevalence of the dual form of malnutrition (overweight mother/underweight child) in the same household and its associated factors in the Gaza Strip.

Methods

A total of 357 mother-child pairs from the same households were surveyed from three different geographical locations in the Gaza Strip, namely, El Remal urban area, Jabalia refugee camp, and Al Qarara rural area. The height and weight of mothers aged 18–50 years were measured, and their body mass index (BMI) was computed. The mothers were categorized according to the criterion of the World Health Organization (WHO) for BMI as overweight if they have a BMI ≥ 25 kg/m². Anthropometric indices were measured for children aged two to five years to classify the underweight children Z-score <-1.

Results

The results showed the prevalence of the dual form of malnutrition in the Gaza Strip was 15.7%, and its associated factors were child’s birth order (OR_adj, 1.50, 95% CL, 1.22, 1.82; p = <0.001), father’s educational (low or medium) levels (OR_adj, 3.19, 95% CL, 1.07, 9.5; p = 0. 036), or (OR_adj, 3.4, 95% CL, 1.12, 10.37; p = 0. 031), high scores of mothers'' nutrition knowledge (OR_adj, 1.23, 95% CL, 1.01, 1.52; p = 0. 048), and low monthly income (OR_adj, 0.28, 95% CL, 0.09, 0.88; p = 0. 030).

Conclusions

The results from this study showed the dual form of malnutrition in the same household was prevalent in the Gaza Strip. This is a public health issue that must be understood and addressed and policy makers must implement an appropriate nutrition action plan to control dual form of malnutrition based on the underlying specific risk factors in the study population. In addition, interventions are needed to help individuals to translate their nutrition knowledge into healthy dietary behaviors.     

Frequency distribution and association of Fat-mass and obesity (FTO) gene SNP rs-9939609 variant with Diabetes Mellitus Type-II population of Hyderabad,Sindh, Pakistan

Background/AimDiabetes Mellitus (DM) is one of the important public health issues worldwide. The Fat mass obesity (FTO) gene rs-9939609 variant identified single nucleotide polymorphism (SNP) with the T to A missense mutation, and has a strong association with T2DM. FTO gene is present on chromosome “16q12.2” comprising of nine exons. FTO gene rs-9939609 a variant is commonly found in the Pakistani Population. The purpose of the study was to alert the population about the rs-9939609 variant SNP, having a strong association with T2DM.Material and MethodsTotal of 190 participants were included in the present cross-sectional study. To collect the samples non-probability convenience technique was used. subjects were recruited and divided into three groups, normal healthy subjects, obese and T2DM. The patients were selected from the Medicine department Jamshoro/Hyderabad by filling the pre-designed proforma, as well as verbal and written consent taken from study participants. To analysed the data ANOVA Post hoc (Tukey-test) was applied for comparison among groups (P < 0.05) and “SNP-STAT” online software was used for frequencies.ResultsThe BMI, neck circumference, waist circumference and lipid profile, fasting blood sugar and HbA1c was found significant (p < 0.001) in both genders as compared to control. Homozygous and heterozygous distribution of allelic and genotyping frequency was found in study participants. 37.9 %T/A, 57.4% T/T, and A/A were 4.7%. The FTO gene rs-9939609 variant amplified and have an increased risk of developing T2DM in the Sindh population. Codominant model odd ratio of T/A showed 2.42 (CI)1.23–3.84, with significant p < 0.032.ConclusionThe present study concluded that the FTO gene SNP rs-9939609 variant was found in the population of Hyderabad, Sindh and having strong association with T2DM and obese individuals. Increase BMI, neck and waist circumference are the biomarkers of obesity and causative factors of T2DM.     

Early Paleogene decapod crustaceans from the Sulaiman and Kirthar Ranges,Pakistan

A set of Paleocene and Eocene decapod crustaceans is described from the Sulaiman and Kirthar Ranges of Pakistan. The fossil crabs Proxicarpilius planifrons Collins and Morris, 1978 and Pakicarcinus orientalis (Collins and Morris, 1978), already known in the Eocene of northern Pakistan, are reported for the first time in the Paleocene of southern Pakistan, enlarging the stratigraphic and the palaeobiogeographical ranges of these species. The callianassid genus Calliax de Saint Laurent, 1973 is reported for the first time in the Paleocene of southern Pakistan; this is the oldest record for the genus.     

Cytosolic and microsomal glutathione-S-transferases from bovine filarial worms Setaria cervi

The work presented here deals with the status of glutathione-S-transferase (GST; E.C. 2.5.1.18), the major enzyme of the phase II detoxification pathway, in bovine filarial worms Setaria cervi. GST activity was determined in various subcellular fractions of bovine filarial worms S. cervi (Bubalus bubalis Linn.) and was found to be mainly associated with cytosolic and microsomal fractions. The respective specific activities of the enzyme from cytosolic and microsomal fractions of S. cervi females were determined to be 0.122 +/- 0.024 and 0.010 +/- 0.0052 micromol/min/mg protein, respectively. Cytosolic enzyme was found to possess optimal activity between pH 6.5 and 7.5, whereas the microsomal enzyme showed a broad pH optima, centered at pH 6.0. Kinetic studies on the cytosolic and microsomal forms of the enzyme revealed significant differences between them, thereby indicating that microsomal GST from S. cervi is quite distinct to the cytosolic protein catalyzing the same reaction.
