Mosquito collections were carried out for a period of one year from January to December 1992 in a pig farm in Sungai Pelek, Selangor, Malaysia. A total of 41,022 mosquitos belonging to 52 species and 20 genera were collected. Culex tritaeniorhynchus and Cx. gelidus, the important vectors, comprised 63% of all mosquitos collected. Both these species were collected in large numbers during the wet...

Atrial fibrillation (AF) occurrence has a known genetic component. Many reports have revealed a correlation between gene mutation and AF, involving genes related to ion channels, connexin (Cx), and those within the angiotensin system. In this study, the correlation between the Cx 40 polymorphism (rs35594137) and AF was investigated in patients with AF in the Xinjiang, Turpan, and Kashi regions ...

Surveys of mosquito larvae were carried out in six areas of Kosrae Island, Kosrae State, the Federated States of Micronesia in December 2009 and June 2012. A total of 962 larvae of six species were collected from 106 natural and artificial habitats. They were identified as Aedes aegypti, Ae. albopictus, Ae. marshallensis, Culex quinquefasciatus, Cx. annulirostris, and Cx. kusaiensis. This is th...

Respiratory syncytial virus (RSV) glycoprotein G mimics fractalkine, a CX(3)C chemokine, which mediates chemotaxis of leukocytes expressing its receptor, CX(3)CR1. The aim of this study was to examine the relationship between RSV infection and expression of perforin and IFN-gamma in CX(3)CR1-expressing peripheral blood CD8(+) T cells. Samples were collected from infants with RSV bronchiolitis, ...

β-Carotene (BC), β-cryptoxanthin (CX) and α-carotene (AC) are common carotenoids that form retinol. The amount of retinol (vitamin A) formed from carotenoid-rich foods should depend chiefly on the bioavailability (absorption and circulation time in the body) of carotenoids from their major food sources and the selectivity and reactivity of carotene cleavage enzymes towards them. The objective o...

The population genetics and phylogenetic relationships of Culex mosquitoes inhabiting the Sonoran Desert region of North America were studied using mitochondrial DNA and microsatellite molecular markers. Phylogenetic analyses of mitochondrial cytochrome c oxidase subunit I (COI) from mosquitoes collected over a wide geographic area, including the Baja California peninsula, and mainland localiti...

We recorded from 118 neurons in the visual sector of the thalamic reticular nucleus (TRN) in anesthetized rabbits. Cells were identified by their location and characteristic burst responses to stimulation of the primary visual cortex (Cx) and optic chiasm (OX) and were classified into two groups. Type I cells had relatively short latencies from both OX and Cx stimulation, and the latency from O...

It is well known that if Fis a field of characteristic zero and K=F(ax,..., ot„) is a finite algebraic extension of F, then K contains a primitive element, i.e. an element a such that F(oti,..., an) = F(a). Moreover, by means of Galois theory, it is possible to characterize those elements of the extension field which are primitive. In the case of finite differentially algebraic extensions the t...

Resting adults Culicidae were collected from January 1992 through January 1993 in several habitats of the Ribeira Valley region. The diversity of species found among them suggested that the vegetation remaining within human settlements favored the survival and the population increase of some mosquitoes. Among there are: Ae. scapularis, Ae. serratus, Cx. (Culex), Cx. nigripalpus and Cx. (Melanoc...
