Chronic Illness, Nutritional Status, and Factors Associated with Malnutrition among Various Age Groups Residing in Urban Areas of Telangana and Rural Areas of Andhra Pradesh.

Malnutrition includes both under-nutrition and over-nutrition, which have negative health impacts and social consequences. The present study aims to understand the demographic dynamics, burden of chronic illnesses, and risk factors associated with malnutrition (stunting, thinness, and obesity) among different age groups in urban and rural areas. Data were collected through a cross-sectional study conducted in an urban area in Hyderabad and four rural villages in Andhra Pradesh. A multivariable mixed-effect logistic regression was used to assess the risk factors associated with malnutrition among different age groups. The final analysis included the data of 10,350 individuals, consisting of 8317 (80.4%) from urban areas and 2033 (19.6%) from rural areas. The number of known cases of hypertension in the urban area was 926 (11.1%) and 114 (5.6%) in the rural areas, and that of diabetes was 511 (6.1%) in the urban area and 104 (5.1%) in the rural areas. The burden of stunting among under-five children and obesity among adults was 33.7% (95% CI; 29.7-37.9) and 47.4% (95% CI; 45.8-49.1), respectively. Adults aged 40-59 years (AOR 1.91; 1.59-2.28) and belonging to a clerical/skilled (AOR 1.32; 1.03-1.71) occupation were at higher odds of obesity compared to their counterparts. Policymakers and health practitioners should consider the insights from our findings to tailor effective interventions to address malnutrition.

The effects of a novel herbal toothpaste on salivary lactate dehydrogenase as a measure of cellular integrity.

OBJECTIVE: Lactate dehydrogenase (LDH) is a critical intracellular enzyme responsible for anaerobic respiration in pyruvate metabolism which becomes detectable in extracellular spaces after cellular breakdown. This clinical investigation examined the effects of brushing with a test toothpaste containing natural ingredients, i.e., clove (Syzygium aromaticum), aloe vera (Aloe barbadensis), amla (Emblica officinalis), neem (Azadirachta indica), tulsi (Ocimum basillicum), and honey (from Apis mellifera), and 0.96% zinc (zinc oxide, zinc citrate) and 0.76% SMFP (1000 ppm F) in a calcium carbonate base formulated with natural ingredients (Ved Shakti, Colgate Palmolive India) and a fluoride toothpaste containing 0.76% SMFP (1000 ppm F) in a calcium carbonate base (Colgate Cavity Protection, Colgate Palmolive; henceforth control) on salivary LDH in conjunction with the assessments of dental plaque and gingivitis representing oral hygiene parameters. MATERIALS AND METHODS: This double-blind, two-cell study enrolled 70 adults (age range 20-59 years). Subjects completed a washout and provided baseline saliva samples for LDH analysis and clinical assessments of dental plaque and gingivitis using the Turesky Modification of Quigley-Hein and Loe-Silness methods respectively. Subjects were randomly assigned to brush their teeth with either the test or control. Post-treatment sample collection and clinical evaluations were conducted after 3 weeks, 6 weeks, and 12 week sof brushing with all assessments conducted 12 h after hygiene. Statistical analyses were conducted independently for each parameter by t-test for within treatment evaluation and analysis of covariance (ANCOVA) for between treatment comparisons. RESULTS: At baseline, treatment groups demonstrated no significant differences for LDH or dental plaque and gingival index scores. Brushing with the test demonstrated progressive reductions in salivary LDH, plaque and gingival index scores over the study duration in comparison to the control. The test demonstrated reductions in LDH of 9.5-15.4% over the study period in comparison to the control representing statistically significant effects (p < 0.05). The test also demonstrated reductions in dental plaque that ranged between 6.4 and 16.2% over the study period and gingivitis reductions that ranged between 8.2 and 23.8% representing statistically significant results (p < 0.05). CONCLUSIONS: Brushing with a novel herbal toothpaste demonstrated significant reductions in salivary LDH representing improvements in cellular integrity with concurrent reductions in dental plaque and gingivitis as compared to the control dentifrice. CLINICAL RELEVANCE: Salivary LDH measurements offer a non-invasive and objective measurement of mucosal cellular integrity complementing other evaluations and clinical assessments such as plaque and gingival index scores.

Pathophysiology of high fat diet induced obesity: impact of probiotic banana juice on obesity associated complications and hepatosteatosis.

The high fat diet alters intestinal microbiota due to increased intestinal permeability and susceptibility to microbial antigens leads to metabolic endotoxemia. But probiotic juices reported for various health benefits. In this background we hypothesized that pectinase treated probiotic banana juice has diverse effects on HFD induced obesity and non-alcoholic steatohepatitis. 20 weeks fed HFD successfully induced obesity and its associated complications in experimental rats. The supplementation of probiotic banana juice for 5 months at a dose of 5 mL/kg bw/day resulted significant decrease (p < 0.05) in body weight (380 ± 0.34), total fat (72 ± 0.8), fat percentage (17 ± 0.07) and fat free mass (165 ± 0.02). Reduction (p < 0.05) in insulin resistance (5.20 ± 0.03), lipid profile (TC 120 ± 0.05; TG 160 ± 0.24; HDL 38 ± 0.03), liver lipid peroxidation (0.7 ± 0.01), hepatic enzyme markers (AST 82 ± 0.06; ALT 78 ± 0.34; ALP 42 ± 0.22), and hepatic steatosis by increasing liver antioxidant potential (CAT 1.4 ± 0.30; GSH 1.04 ± 0.04; SOD 0.82 ± 0.22) with normal hepatic triglycerides (15 ± 0.02) and glycogen (0.022 ± 0.15) contents and also showed normal liver size, less accumulation of lipid droplets with only a few congestion. It is concluded that the increased intestinal S. cerevisiae yeast can switch anti-obesity, antidiabetic, antioxidative stress, antioxidant and anti-hepatosteatosis effect. This study results will have significant implications for treatment of NAFLD.

Protein samples were analyzed by 2-D, MALDI-TOF combined with MS access. In 2-D electrophoresis, eight differentially expressed proteins were identified: five up-regulated, two down-regulated and one newly expressed protein. Protein spots were digested with trypsin for MALDI-TOF-MS analysis; protein sequences were obtained from MASCOT search. Sequences were aligned with template using Swiss Model server. Phyre-2 was used to predict homology modeling, RasMol was used to analyze the modeling structures, PSVS server was utilized to validate the protein structure by Ramachandran's plot analysis, physical and chemical properties were analyzed using ProtParam server, Phylogenetic tree was constructed by Mega4. UniProt search helps to find protein functional information of differentially expressed proteins, involved in catalytic activities, regulation mechanisms, DNA damage stimulus, anti-termination and termination process, protein binding, electron transport mechanism, and cell signaling process functions. A detailed exploration of the proteins under cocoti palm wine stress have provided the composition, structure and functions of the expressed proteins for further investigation.

Regional variation in utilization of Antenatal care services in the state of Andhra Pradesh.

BACKGROUND: Delivery of maternal health care services is a major challenge to the health system in developing countries. Provision of antenatal care (ANC) services is the major function of public health delivery system in India to improve maternal health outcomes and its impact on maternal morbidity and mortality. Studies are lack in documenting variation in utilization of ANC services between geographical regions of Andhra Pradesh (AP). OBJECTIVE: The objective of this study is to assess variation in utilization of ANC services stratified by geographical region, type of delivery and determinants of utilization of ANC services in AP. METHODOLOGY: It is a cross-sectional study of District Level Household and Facility Survey-4 of the state of AP. Multistage, stratified and probability proportional to size sample with replacement was used. Around 3982 women who delivered after the year 2007 were considered for analysis. Binomial logistic regression was carried out to determine association of demographic, system level variables with adequate ANC. RESULTS: Study reveals wide variation across four regions of AP in utilization of ANC services. Reception of adequate ANC was low in Rayalaseema region (27.9%) and high in North-coastal region (42.4%). The utilization of private health facilities for ANC services were highest in South-coastal region (73.2%) and lowest in North-coastal region (43.2%). CONCLUSION: Policy measures are to be adopted and implemented by government to address the demand-supply imbalance such as public health infrastructure and quality of services in underperforming districts of AP and to increase outreach of current programs by engaging communities.

Suppressive activity of a viral histone H4 against two host chromatin remodelling factors: lysine demethylase and SWI/SNF.

Histone H4, a nucleosome subunit in eukaryotes, plays crucial roles in DNA package and regulation of gene expression through covalent modification. A viral histone H4 encoded in Cotesia plutellae bracovirus (CpBV), a polydnavirus, is called CpBV-H4. It is highly homologous to other histone H4 proteins excepting 38 extra amino acid residues in the N terminus. CpBV-H4 can form octamer with other histone subunits and alter host gene expression. In this study, CpBV-H4 was transiently expressed in a natural host (Plutella xylostella) and its suppressive activity on host gene expression was evaluated by the suppressive subtractive hybridization (SSH) technique. The SSH targets down-regulated by CpBV-H4 were read with the 454 pyrosequencing platform and annotated using the genome of P. xylostella. The down-regulated genes (610 contigs) were annotated in most functional categories based on gene ontology. Among these SSH targets, 115 genes were functionally distinct, including two chromatin remodelling factors: a lysine-specific demethylase (Px-KDM) and a chromatin remodelling complex [Px-SWI/SNF (SWItch/Sucrose Non-Fermentable)]. Px-KDM was highly expressed in all tested tissues during the entire larval period. Suppression of Px-KDM expression by specific RNA interference (RNAi) significantly (P<0.05) reduced haemocyte nodule formation in response to immune challenge and impaired both larval and pupal development. Px-SWI/SNF was expressed in all developmental stages. Suppression of Px-SWI/SNF expression by RNAi reduced cellular immune response and interfered with adult metamorphosis. These results suggest that CpBV-H4 can alter host gene expression by interfering with chromatin modification and remodelling factors in addition to its direct epigenetic control activity.

Spectroscopic studies (FT-IR, FT-Raman, UV-Visible), normal co-ordinate analysis, first-order hyperpolarizability and HOMO, LUMO studies of 3,4-dichlorobenzophenone by using Density Functional Methods.

The vibrational frequencies of 3,4-dichlorobenzophenone (DCLBP) were obtained from the FT-IR and Raman spectral data, and evaluated based on the Density Functional Theory using the standard method B3LYP with 6-311+G(d,p) as the basis set. On the basis of potential energy distribution together with the normal-co-ordinate analysis and following the scaled quantum mechanical force methodology, the assignments for the various frequencies were described. The values of the electric dipole moment (µ) and the first-order hyperpolarizability (ß) of the molecule were computed. The UV-absorption spectrum was also recorded to study the electronic transitions. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecule. The NBO analysis, to study the intramolecular hyperconjugative interactions, was carried out. Mulliken's net charges were evaluated. The MEP and thermodynamic properties were also calculated. The electron density-based local reactivity descriptor, such as Fukui functions, was calculated to explain the chemical selectivity or reactivity site in 3,4-dichlorobenzophenone.

BACKGROUND: To assess the knowledge, attitude, and practice of ergonomics among dental professionals of Hubli-Dharwad twin cities, India. METHODS: Investigator-developed, self-administered, closed-ended questionnaire assessing knowledge, attitude, and practices regarding ergonomics during dental practice was filled in by undergraduates, house surgeons, postgraduates, and faculty members of dental institutions and private practitioners from Hubli-Dharwad twin cities. RESULTS: Data were collected from a total of 250 participants, 50 belonging to each academic group. Overall mean knowledge, attitude, and practice scores were 52%, 75%, and 55%, respectively. Significant correlation was found for age with attitude (chi2 = 10.734, p = 0.030) and behavior (chi2 = 12.984, p = 0.011). Marital status was significantly associated with all the three domains; knowledge (chi2 = 29.369, p = 0.000), attitude (chi2 = 29.023, p = 0.000), and practices (chi2 = 13.648, p = 0.009). CONCLUSION: Participants had considerable awareness and behavior toward ergonomics in dental practice. The high attitude score indicates stronger acceptance of ergonomics principles and guidelines during routine dental procedures. The current study highlights the situation of ergonomics in dental practice in the form of knowledge, attitude, and practices.

Knowledge about prevention of oral cancer and gum disease among school teachers in Dharwad, India.

OBJECTIVE: To assess the knowledge of primary school teachers in Dharwad, India, regarding the prevention of oral cancer and gum disease. MATERIALS AND METHODS: In this cross sectional study a self administered questionnaire was used for data collection. A total of 184 school teachers were selected for the study. A response rate of 96.7% (n = 178) was obtained. RESULTS: Of the respondents, 36.5% (n = 65) had poor knowledge, while 27.5% had good knowledge regarding the prevention of oral cancer and gum disease. School teachers with postgraduate qualification were better informed with regard to the prevention of oral diseases as compared to those with only a bachelor degree. Factors such as education, sex, and type of institutional funding (public/private) were significantly correlated with the level of knowledge (R2 = 0.1128; P < 0.05). CONCLUSION: School teachers need to be motivated to improve their awareness and knowledge about the prevention of oral cancer and gum diseases, particularly the younger teachers and those with only bachelor degrees. Establishment of school-based oral-health promotion programs in India is urgently required.

Antihyperglycemic and antihyperlipidemic activities of 2-(4-[(2-hydroxybenzyl) amino]-phenyl amino-methyl)-phenol in STZ induced diabetic rats.

Oral administration of 2-(4-[(2-hydroxybenzyl) amino]-phenyl amino-methyl)-phenol (HBPMP) (30 mg/kg) to Streptozotocin (STZ) rats produced significant antidiabetic activity after 6 h of HBPMP administration. Treatment of the STZ rats with HBPMP (30 mg/kg/day) for 30 days resulted in a significant decrease in their Fasting Blood Glucose (FBG), Serum Total Cholesterol (TC), Low Density Lipoprotein-Cholesterol (LDL-C), Very Low Density Lipoprotein-Cholesterol (VLDL-C) and triglycerides (TG) along with an increase in serum High Density Lipoprotein-Cholesterol (HDL-C) levels. Activities of Serum Aspartate transaminase (AST), Alanine transaminase (ALT) and Alkaline phosphatase (ALP) and levels of blood urea and creatinine were improved to near normal levels in the treated STZ rats indicating the protective role of the HBPMP against liver and kidney damage and its non-toxic property. In conclusion, HBPMP possesses antihyperglycemic and antihyperlipidemic activities.

RNA interference of ß1 integrin subunit impairs development and immune responses of the beet armyworm, Spodoptera exigua.

Integrin is a cell surface protein that is composed of α and ß heterodimer and mediates cell interaction with extracellular matrix or other cells including microbial pathogens. A full length cDNA sequence (2862 bp) of a ß1 subunit integrin (ßSe1) was cloned from the beet armyworm, Spodoptera exigua. Phylogenetic analysis showed that ßSe1 was clustered with other insect ß integrin subunits with the highest amino acid sequence identity (98.3%) to ß1 of Spodoptera litura. Structural analysis of the deduced amino acid sequence indicated that ßSe1 possessed all functional domains known in other insect ß1 integrins. RT-PCR analysis showed that ßSe1 was expressed in all developmental stages and all tested tissues of S. exigua. Its expression was further upregulated in hemocytes by injections of various microbes from quantitative RT-PCR analysis. Injection of double-stranded ßSe1 RNA (dsRNA(ßSe1)) into late instar S. exigua suppressed ßSe1 expression and resulted in significant reduction in pupal weight. The dsRNA(ßSe1) injection significantly impaired hemocyte-spreading and nodule formation of S. exigua in response to bacterial challenge. Furthermore, oral ingestion of dsRNA(ßSe1) induced reduction of ßSe1 expression in midgut and resulted in significant mortality of S. exigua during immature development. These results suggest that ßSe1 plays crucial roles in performing cellular immune responses as well as larval development in S. exigua.

Temporal bacterial diversity and detection of putative methanotrophs in surface mats of Lonar crater lake.

The phylogenetic diversity of bacterial communities in microbial mats of two different seasons from saline and hyperalkaline Lonar Lake was investigated using 16S rRNA gene library analysis. Arthrospira (Cyanobacteria) related clones (>80% of total clones) dominated libraries of both the seasons. Clear differences were found in both the seasons as the operational taxonomic units (OTUs) related to Fusibacter (LAI-1 and LAI-59) and Tindallia magadiensis (LAI-27) found in post-monsoon were not found in the pre-monsoon library. Likewise, OTUs related to Planococcus rifietensis (LAII-67), Bordetella hinzii (LAII-2) and Methylobacterium variabile (LAII-25) found in the pre-monsoon were not found in post-monsoon. The study was extended to identify methanotrophs in the surface mats. Libraries constructed with type I and type II methanotroph specific 16S rRNA gene primers showed the presence of clones (LAMI-99 and LAMII-2) closely related to Methylomicrobium buryaticum and Beijerinckiaceae family members. Denaturing gradient gel electrophoresis (DGGE) fingerprinting based on protein-coding genes (pmoA and mxaF) further confirmed the detection of Methylomicrobium sp. Hence, we report here for the first time the detection of putative methanotrophs in surface mats of Lonar Lake. The finding of clones related to organisms with interesting functional attributes such as assimilation of C(1) compounds (LAII-25, LAMI-39, LAMI-99 and LAMII-2), non-sulfur photosynthetic bacteria (LAMII-43) and clones distantly affiliated to organisms of heavily polluted environments (LAI-59 and LAMII-52), is of significant note. These preliminary results would direct future studies on the functional dynamics of microbial mat associated food web chain in the extreme environment.

Electricity generation using chocolate industry wastewater and its treatment in activated sludge based microbial fuel cell and analysis of developed microbial community in the anode chamber.

Feasibility of using chocolate industry wastewater as a substrate for electricity generation using activated sludge as a source of microorganisms was investigated in two-chambered microbial fuel cell. The maximum current generated with membrane and salt bridge MFCs was 3.02 and 2.3 A/m(2), respectively, at 100 ohms external resistance, whereas the maximum current generated in glucose powered MFC was 3.1 A/m(2). The use of chocolate industry wastewater in cathode chamber was promising with 4.1 mA current output. Significant reduction in COD, BOD, total solids and total dissolved solids of wastewater by 75%, 65%, 68%, 50%, respectively, indicated effective wastewater treatment in batch experiments. The 16S rDNA analysis of anode biofilm and suspended cells revealed predominance of beta-Proteobacteria clones with 50.6% followed by unclassified bacteria (9.9%), alpha-Proteobacteria (9.1%), other Proteobacteria (9%), Planctomycetes (5.8%), Firmicutes (4.9%), Nitrospora (3.3%), Spirochaetes (3.3%), Bacteroides (2.4%) and gamma-Proteobacteria (0.8%). Diverse bacterial groups represented as members of the anode chamber community.

Phylogenetic analysis of methanogenic enrichment cultures obtained from Lonar Lake in India: isolation of Methanocalculus sp. and Methanoculleus sp.

The diversity of methanogenic archaea in enrichment cultures established from the sediments of Lonar Lake (India), a soda lake having pH approximately 10, was investigated using 16S rDNA molecular phylogenetic approach. Methanogenic enrichment cultures were developed in a medium that simulated conditions of soda lake with three different substrates viz., H(2):CO(2), sodium acetate, and trimethylamine (TMA), at alkaline pH. Archaeal 16S rRNA clone libraries were generated from enrichment cultures and 13 RFLP groups were obtained. Representative sequence analysis of each RFLP group indicated that the majority of the 16S rRNA gene sequences were phylogenetically affiliated with uncultured Archaea. Some of the groups may belong to new archaeal genera or families. Three RFLP groups were related to Methanoculleus sp, while two related to Methanocalculus sp. 16S rRNA gene sequences found in Lonar Lake were different from sequences reported from other soda lakes and more similar to those of oil reservoirs, palm oil waste treatment digesters, and paddy fields. In culture-based studies, three isolates were obtained. Two of these were related to Methanoculleus sp. IIE1 and one to Methanocalculus sp. 01F97C. These results clearly show that the Lonar Lake ecosystem harbors unexplored methanogens.

Molecular analyses of microbial diversity associated with the Lonar soda lake in India: an impact crater in a basalt area.

The prokaryotic diversity associated with an Indian soda lake (Lonar Crater Lake) located in a basaltic soil area was investigated using a culture-independent approach. Community DNA was extracted directly from four sediment samples obtained by coring to depths of 10-20 cm. Small subunit rRNA genes (16S rDNA) were amplified by PCR using primers specific to the domains Bacteria and Archaea. The PCR products were cloned and sequenced. For the bacterial rDNA clone library, 500 clones were randomly selected for further analysis. After restriction fragment length polymorphism (RFLP) analysis and subsequent sequencing, a total of 44 unique phylotypes were obtained. These phylotypes spanned a wide range within the domain Bacteria, occupying eight major lineages/phyla. 34% of the clones were classified as firmicutes. The other clones were grouped into proteobacteria (29.5%), actinobacteria (6.8%), deinococcus-thermus (4.5%), cytophages-flavobacterium-bacteroidetes (13.3%), planctomycetes (6.8%), cyanobacteria (4.5%) and spirochetes (2.27%). In the case of the archaeal 16S rDNA library, analysis of 250 randomly selected clones revealed the presence of 13 distinct phylotypes; 5 phylotypes were associated with Crenarchaeota and 8 with Euryarchaeota. Most of the euryarchaeota sequences were related to methanogens. Findings from this molecular study of a site investigated for the first time have revealed the presence of a highly diverse bacterial population and a comparatively less diverse archaeal population. The majority ( approximately 80%) of the cloned sequences show little affiliation with known taxa (<97% sequence similarity) and may represent novel taxa/sequences and organisms specifically adapted to this basaltic soda lake environment. Diversity analyses demonstrate greater diversity and evenness of bacterial species compared to a skewed representation of species for Archaea.
