Indian Academy of Pediatrics Consensus Guidelines on Preconception Care.

Justification: The preconception period is the earliest window of opportunity to ensure optimal human development.  Pregnancy and childbirth outcomes can be improved by interventions offered to support the health and well-being of women and couples prior to conception. Thus, preconception care is essential in preparing for the first thousand days of life.

Prevalence of Non-Alcoholic Fatty Liver Disease in Urban Adult Population in a Tertiary Care Center, Chennai.

Background: Non-alcoholic fatty liver disease (NAFLD) is becoming one of the most common liver diseases among the Indian population. The predisposing factors for NAFLD are diet, lifestyle modifications, and lack of exercise. There is a paucity of research on NAFLD in the South Indian population.

Transformation of used aluminium foil food container into AlOOH nanoflakes with high catalytic activity in anionic azo dye reduction.

Synthesis of aluminium-based nanomaterials from aluminium-waste has received huge attention in current scientific research. Herein, an attempt was made to convert aluminium foil food container into aluminium oxyhydroxide (AlOOH) nanoparticles by a precipitation method. X-ray diffraction (XRD), spectroscopic and electron microscopic studies were employed to characterize impure AlOOH (containing sodium chloride, NaCl) and pure AlOOH samples.

Comparison of Microalbuminuria Status in Type 2 Diabetes Mellitus Patients With Chronic Periodontitis: A Cross-Sectional Study.

Background Diabetes has increased the risk for various other ailments in various organs of the body. This can be contributing to periodontitis also as it is the sixth complication related to diabetes mellitus. There is a bidirectional relationship between both.

Conversion of carbon dioxide to resorcylic acid under ultrasonication by Kolbe-Schmitt reaction.

The present work focuses on a new approach for the synthesis of β-resorcylic acid based on Kolbe-Schmitt reaction using carbon dioxide under ultrasonic and mild condition. The Kolbe-Schmitt reaction is a process for the synthesis of β-resorcylic acid (2,4-dihydroxybenzoic acid) from resorcinol in aqueous potassium hydroxide solution with gaseous CO2. The influences of carbonation time, flow rate of CO2 and the molar ratio of resorcinol/potassium hydroxide on the yield percentage of resorcylic acid were investigated.

Properties of spray pyrolised ZnO:Sn thin films and their antibacterial activity.

Tin doped zinc oxide (ZnO:Sn) thin films were deposited onto glass substrates by the spray pyrolysis technique with the substrate temperature 400 °C. The structural, optical, photoluminescence (PL) properties and morphological studies were investigated for the films deposited with various doping concentration (0, 2, 4, 6 and 8 at.%) of tin.

Significance of ferritin in recurrent oral ulceration.

Background: Ferritin is the storage form of iron. Hence, the sensitive test which can be used for diagnosing iron deficiency anaemia is estimation of ferritin in serum. One of the causative factors of oral ulceration is nutritional deficiency, which includes iron also.

Utilization Article of CHC (Complete Health Checkup) Type Charts to Improve the Students' Understanding of Clinical Pathology.

Background: Second year undergraduate medical students lack an integrated approach towards the basic laboratory data. So, they find it difficult when analytical exercises are asked for in pathology practical examinations. A Complete Health Checkup (CHC) is one exercise where an individual undergoes a clinical examination, followed by various basic laboratory tests, along with other tests like ECG, X-ray and USG of the abdomen.

IgE- and IgG mediated severe anaphylactic platelet transfusion reaction in a known case of cerebral malaria.

Background: Allergic reactions occur commonly in transfusion practice. However, severe anaphylactic reactions are rare; anti-IgA (IgA: Immunoglobulin A) in IgA-deficient patients is one of the well-illustrated and reported causes for such reactions. However, IgE-mediated hypersensitivity reaction through blood component transfusion may be caused in parasitic hyperimmunization for IgG and IgE antibodies.

Serum carbohydrate deficient transferrin as a sensitive marker in diagnosing alcohol abuse: a case - control study.

Background: Alcoholism is a major problem in India thereby causing a heavy toll on the health related expenditure of the country. Detection of alcohol abuse rely mainly on clinical details which is sometimes inaccurate or unreliable and hence using a specific diagnostic parameter might be of immense use not only for early diagnosis but also during follow up of the cases.

Aims And Objectives: This case control study aimed at evaluating the usefulness of Carbohydrate Deficient Transferrin (CDT) as a sensitive marker to diagnose alcohol abuse.

Effect of iron deficiency on glycation of haemoglobin in nondiabetics.

Background: Protein glycation is a spontaneous reaction that is believed to play a key role in the pathogenesis of many clinical disorders. The glycation of proteins is enhanced by elevated glucose concentrations. The major form of protein glycation with a clinical consideration is glycated haemoglobin (HbA1c).

The red cell distribution width as a sensitive biomarker for assessing the pulmonary function in automobile welders- a cross sectional study.

Context: Welding fumes are considered as a risk factor for pulmonary diseases and a periodic spirometry is essential to evaluate the lung function of the welders. The Red Cell Distribution Width (RDW) is a red cell measurement which is provided by automated haematology analyzers. It reflects the range of the red cell sizes which are measured within a sample.

The reference intervals for the haematological parameters in healthy adult population of chennai, southern India.

Background: The haematological parameters are influenced by various factors like age, ethnicity, diet, genetic and gender differences and hence it is important to define the specific reference values with regards to the age, gender and the region. The indices like the Red Cell Distribution Width (RDW), the Mean Platelet Volume (MPV) and the Platelet Distribution Width (PDW) are newer haematological parameters which are calculated by automated haematology analyzers. There is an increasing evidence that these are clinically valuable bio markers.

Study of fluorescence quenching of Barley α-amylase.

The fluorescence quenching of Barley α-amylase by acrylamide and succinimide has been studied in water using steady-state and time-resolved fluorescence techniques. The steady-state fluorescence quenching technique has been performed in three different pHs (i.e.

Interaction of potassium mono and di phosphates with bovine serum albumin studied by fluorescence quenching method.

The interactions between potassium mono and di phosphates and bovine serum albumin (BSA) were studied using fluorescence spectroscopy (FS) and ultraviolet spectroscopy (UV). The experimental results showed that the potassium mono and di phosphates could insert into the BSA and quench the inner fluorescence of BSA by forming the potassium mono phosphate-BSA and pottassium di phosphate-BSA complexes. It was found that the static quenching was the main reason leading to the fluorescence quenching.

Spectroscopic characterization studies of 1-methyl indole with benzene derivatives.

The NMR and fluorescence quenching of benzene, chlorobenzene and methoxybenzene in acetonitril and 2-propanol solvents have been carried out with a view to understand the quenching mechanisms. The quenching is found to be appreciable and shows positive derivation in the stern-volmer plots. UV absorbance is used to measure the excitation wavelength.
