Intrahousehold Food Distribution in the Philippines: A Food Share Over Energy Share Perspective.

Background: Studies on intrahousehold inequality in food distribution typically have focused on the distribution of total energy within the household. While some members within the household can satiate their hunger primarily from the consumption of inexpensive staple food items, others can consume a significantly larger share of much more expensive nonstaple food items rich in bioavailable micronutrients. This potential inequality, which significantly impacts micronutrient malnutrition in developing countries, can be influenced by the gender-related sociocultural norms.

Genetic barcodes for species identification and phylogenetic estimation in ghost spiders (Araneae: Anyphaenidae: Amaurobioidinae).

The identification of spider species presents many challenges, since in most cases the characters used are from genital structures that are only fully developed in the adult stage, hence the identification of immatures is most often not possible. Additionally, these structures usually also present some intra-specific variability, which in some cases makes the identification of closely related species difficult. The genetic barcode technique (DNA barcodes), based on sequencing of the mitochondrial marker cytochrome c oxidase subunit I (COI ), has proven a useful, complementary tool to overcome these limitations.

Catalytic Selective Oxidation of β-O-4 Bond in Phenethoxybenzene as a Lignin Model Using (TBA)[PMoVO] Nanocatalyst: Optimization of Operational Conditions.

The catalytic oxidation of phenethoxybenzene as a lignin model compound with a β-O-4 bond was conducted using the Keggin-type polyoxometalate nanocatalyst (TBA)[PMoVO]. The optimization of the process's operational conditions was carried out using response surface methodology. The statistically significant variables in the process were determined using a fractional factorial design.

Medusa's Wrath: Bleeding Giant Scalp Arteriovenous Malformation in an Adult: A Case Report.

Background: Scalp arteriovenous malformation (AVM) is a rare congenital disease that may present with massive bleeding. To date, surgical excision remains the definitive management. However, the procedure could lead to intraoperative bleeding due to the tumor's high blood flow and complex vascularity.
