Energy requirements of adults.

OBJECTIVES: To describe issues related to energy requirements of free living adults and discuss the importance of basal metabolic rate (BMR) and their relationships to total energy expenditure (TEE ) and physical activity level (PAL, derived as TEE/BMR) and to determine the influence of body weight, height, age and sex. DESIGN: Based on a review of the literature, this paper examines the variability in BMR due to methodology, ethnicity, migration and adaptation (both metabolic and behavioural) due to changes in nutritional status. Collates and compiles data on measurements of TEE in free living healthy adults, to arrive at limits and to compare TEE of populations with different life-styles. RESULTS AND CONCLUSIONS: The constancy of BMR and its validity as a reliable predictor of TEE in adults as well as the validity of PAL as an index of TEE adjusted for BMR and thus its use to categorise the physical activity pattern and lifestyle of an individual was confirmed. The limits of human daily energy expenditure at around 1.2 x BMR and 4.5 x BMR based on measurements made in free living adults have been reported in the literature. A large and robust database now exists of energy expenditure measurements obtained by the doubly labelled water method in the scientific literature and the data shows that, in general, levels of energy expenditure are similar to the recommendations for energy requirements adopted by FAO/WHO/UNU (1985). The review also confirms that metabolic adaptation to energy restriction is not an important factor that needs to be considered when recommending energy requirements for adults in developing countries

Ganglioneuroma Always A Histopathological Diagnosis

Neuroblastoma, ganglioneuroblastoma and ganglioneuroma arise from sympathetic tissue in the neck, posterior mediastinum, adrenal gland, retroperitoneum and pelvis Ganglioneuromas are commonly seen in childhood. They are highly differentiated benign tumors and are compatible with long-term disease free survival. Retroperitoneal localization is relatively frequent for these tumors. Due to its rarity and lack of specific radiological findings diagnosis is always postoperative. Here, we present a case of Retroperitoneal ganglioneuroma which was undiagnosed before surgery

Hydrazide derivatives: an overview of their inhibition activity against acid corrosion of mild steel

This paper gives an overview of the application of hydrazide derivatives in acid media as corrosion inhibitors of mild steel. In chemical and petrochemical industries, mild steel is the major constructional material widely used. Acid solutions have been commonly used in these industries as pickling agents to remove rust or any scale from the mild steel surface. The excessive dissolution of mild steel in such aggressive medium can be best controlled by addition of suitable organic inhibitors. Hydrazide derivatives are widely used in such applications as mild steel corrosion inhibitors. The various factors which influence the corrosion inhibition efficiency of different hydrazide derivatives have been discussed. The information provided is useful for various industries where corrosion inhibitors are needed to protect mild steel structures which are being exposed to hydrochloric or sulphuric acid solutions.Keywords: Hydrazide derivatives, mild steel, acid media, corrosion inhibition, adsorptio

Total Thiols and MDA Levels in Patients with Acute Myocardial Infarction Before and After Reperfusion Therapy

Background: Reactive oxygen species have been implicated in the pathogenesis of ischemic and reperfusion injury. In the current work we have measured malondialdehyde (MDA), total thiols, total CK, CK-MB and AST in ECG proven acute myocardial infarction (AMI) patients immediately after admission and 24 hours after administration of thrombolytic agent streptokinase, and in healthy controls. Methods: Blood samples from 44 AMI patients and 25 age and sex matched healthy controls were obtained and analyzed for MDA, total thiols using spectrophotometric methods and cardiac enzymes CK, CK-MB and AST using automated analyzer. Results: We have found significant increase in MDA, CPK, CK-MB, AST (p< 0.001) and significant decrease in total thiols (p<0.001) in AMI patients after thrombolytic therapy compared to values at admission, and healthy controls. MDA correlated negatively with total thiols (r = - 0.333, p<0.05) and positively with CK-MB (r = 0.491, p<0.01) in AMI patients after thrombolytic therapy. Conclusions: Reperfusion following thrombolytic therapy increases reactive oxygen species with concomitant decrease in antioxidant total thiols

Bumper catch of mackerel at Panjim, Goa

Mackeral fishery at Panjim during this season was exceptionally good ranging from 14 to 19 cm size. On an average each purse-seine landed a catch of about 3 tonnes of mackerel practically flooding the jetty. The prices crashed to Rs. 10/- per basket weighing 40 kg. Sixty seven purse-seiners , each one with 2 to 4 tonnes of mackerel landed on a single day and on next day 39 purse-seiners landed the catch at a rate of 1.5 to 5 tonnes by each boat

Ovarian Fibroma with Meigs Syndrome associated with Elevated CA125 - A Rare Case

Postmenopausal women with solid adnexal masses, ascites and pleural effusion with elevated CA 125 are highly suggestive for malignant ovarian tumor. However in literature 28 cases Meigs syndrome (Benign ovarian tumor, ascites and right pleural effusion) with raised CA 125 have been reported. We report a case of Meigs syndrome caused by right ovarian fibroma with elevated serum CA125 level in a postmenopausal woma

Primary Fallopian Tube Carcinoma

Primary Fallopian Tube Carcinoma (PFTC) is rare and accounts for about 0.3% of all gynecologic cancers. Less than 1500 cases have been reported in the literature. It arises in postmenopausal women and typically presents with abdominal pelvic pain, vaginal bleeding and watery discharge. However, a correct diagnosis is rarely achieved preoperative, and in many cases, the diagnosis is made after incidental surgery for unrelated conditions commonly being ovarian carcinoma . Compared with ovarian carcinoma, PFTC more often presents at early stages, but it has a worse prognosis. PFTC is usually managed in the same manner as ovarian cancer. We report a case of Left PFTC that presented as Left ovarian mass, and we briefly review the literature

Effect Of Oestradiol On Mouse Vaginal Epithelium

Oestradiol which induces the proliferation of the vaginal epithelium is used in the oestrogen replacement therapy for menopausal and postmenopausal disorders. The exact onset of induced cell proliferation and recovery to the controlled level has not been reported before. Hence this study was done in ovariectomised mice and the period of cellular response to ethinyl estradiol, a semisynthetic ester (0.025mg/kg) was recorded. The vaginal epithelium was studied for histological changes and incidence of mitotic figures. The onset of proliferation started at 4h after exposure and reached its maximum at 32h and declined gradually thereafter to reach the base level at 60h
