Experts Warn Against Recommending Compounded Bioidentical Hormones in Menopause

Posted on

Compounded bioidentical hormones (cBHT) are risky at best and most likely hazardous, and should be regulated by the Food and Drug Administration just as other menopausal hormone therapy products are,1 according to JoAnn E. Manson, MD, DrPH, professor of medicine at Harvard Medical School and chief of preventive medicine at Brigham and Women’s Hospital, and Cynthia A. Stuenkel, MD, clinical professor of medicine, at the University of California San Diego School of Medicine.to read more please visit https://www.scitechnol.com/abstract/effect-of-brain-training-on-eyehand-coordination-activities-in-elderly-patients-for-stress-and-type-2-diabetes-mellitus-6509.html

Biochemical Composition of an Etuarine Oyster, Thais califera Var. coronata and Senilia senilis in a Mangrove Swamp of Eastern Obolo, Niger Delta

Posted on

The comparative study on the biochemical composition of Ostrea tulipa (Lamarck), Thais califera var. coronata (Lamarck) and Senilia senilis (Linnaeus) were investigated in the mangrove swamp of Eastern Obolo, Niger Delta. Samples were handpicked during low tide in the month of December, 2015, washed and separated the tissues from the shell. The proximate composition revealed that protein content was high in S. senilis (80.32%) and low in T. coronata (76.54%). Carbohydrate and Crude fibre content were significantly low in all the species. Vitamins analysis revealed that Vit. A content were high in all the species with S. senilis recording the highest (1684.24 mg/100 g). Vit. B1 was not detected in O. tulipa while Vit. B2 was relatively low in all the species. Vit. C, D and E contents were high in S. senilis compared to the other species. The mineral contents composition showed that iron was not detected in S. senilis and O. tulipa. Calcium content was high in S. senilis (426.67 mg/100 g) and O. tulipa (400.00 mg/100 g) compared to T. coronata (274.29 mg/100 g) while sodium content was very high in T. coronate (1310 mg/100 g) than others. The composition of essential amino acid in the species revealed a total concentration of 23.056 mg/100 g in S. senilis, 15.451 mg/100 g in O. tulipa and 8.061 mg/100 g in T. coronata, whereas the non-essential recorded highest concentration in S. senilis (20.037 mg/100 g) compared to others. Therefore we recommend these species for consumption, culture, conservation and proper management in the area.

Does Shells Type Restraining Influence Relative Growth Rates of Clibanarius antillensis (Crustacea: Decapoda: Anomura: Diogenidae)?

Posted on

This study aimed to analyze the relation of gastropod shells and hermit crab sizes and the relative growth (rates) of Clibanarius antillensis based on the allometric technique. We sampled hermit crabs on a rocky shore from Cairu municipality, coast of Bahia, Brazil in 2011. These hermit crabs only occupied shells of one species of gastropod, Cerithium atratum, despite occurrence of other gastropod species in the area. The relative growth of C. antillensis had a negative allometric standard for shield length vs. shield width, which indicates that the carapace shield grows at a higher rate in length than in width. This finding is the opposite of that found in other studies for hermit crabs. We suspect that the use of only one gastropod shell type may be modulating growth rates of C. antillensis at the study site.

Space radiation more hazardous: Implication sfor astronauts and satellites

Posted on Updated on

It might sound like something from a science fiction plot – astronauts traveling into deep space being bombarded by cosmic rays – but radiation exposure is science fact. As future missions look to travel back to the moon or even to Mars, new research cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology.

Growing need for urban forests as urban land expands

Posted on Updated on

A project states that urban land in Lower 48 states will more than double between 2010 and 2060, which will affect forest and agricultural lands that are being converted to urban uses as well as expand the importance of urban forests in relation to environmental quality and human well-being.

Scientists discover key #gene for producing marine molecule with huge #environmental impacts

Posted on

Researchers have discovered a key gene for the synthesis of one of the world’s most abundant sulfur molecules — Dimethylsulfoniopropionate (DMSP). DMSP is an important nutrient in marine environments with more than one billion tonnes produced annually by marine phytoplankton, seaweed and bacteria. The discovery represents a huge step forward in the field of sulfur cycling in marine environments. It could also allow scientists to better predict the impact of climate change on DMSP production.

Large-scale #environmental variation affects reproduction and survival of plants

Posted on

A new analysis looks at how rates of reproduction and survival of 26 shrub species with fire-dependent life cycles in the Cape Floristic Region in South Africa respond to environmental variation. The study incorporates multiple environmental drivers–notably climate and fire–at large spatial scales for a significant number of species and populations. The findings provide important insights on how interactions among these drivers shape the population dynamics of plants.
