Horseshoe lung is an uncommon congenital malformation in which the bases of the right and the left lungs are fused to each other by a narrow isthmus posterior to the cardiac apex (1). There have been 52 case reports in the English literature. Holt-Oram syndrome is characterized by cardiac septation defects and preaxial radial ray abnormalities (2). To our knowledge, it is the first report of ho...

Holt-Oram syndrome is an autosomal dominant disorder characterised by radial ray and congenital heart defects. Recently, a gene for this disorder has been identified on chromosome 12q24.1, encoding a T box transcription factor. However, the functional role of the gene product is not completely understood. We present results of neurological, radiological, and muscle magnetic resonance imaging (M...

We propose new versions of Holt-Winters (HW) and seasonal Holt-Winters (SHW) time series forecasting algorithms. The exponential smoothing construct is identical to HW/SHW, except that the coefficients are estimated by minimizing a given quantile error criterion, instead of the usual squared errors. We call these versions quantile HW/SHW (QHW/QSHW), which amounts to performing HW/SHW under an a...

Farmers’ risk preferences play an important role in agricultural production decisions, takers means the farmers who are willing to take risky decisions farming, aversion attitude of reluctance farming. Climatic change effects all regions across globe and causes substantial agitations that can be expected natural systems have foreseeable influences on economic upland through both direct indirect...

Despite a flood of research on the topic, rates of allergy and allergy-induced asthma continue to climb in most industrialized nations. Holt, a professor at the Telethon Institute for Child Health Research in Perth, Australia, wants to reverse that trend. To accomplish this, he needs to know what triggers airborne allergy and asthma, starting at the moment babies draw their first breath. He's c...

Holt-Oram syndrome is an autosomal-dominant condition characterized by congenital cardiac and forelimb anomalies. It is caused by mutations of the TBX5 gene, a member of the T-box family that encodes a transcription factor. Molecular studies have demonstrated that mutations predicted to create null alleles cause substantial abnormalities in both the limbs and heart, and that missense mutations ...

BACKGROUND Much of the developing world, particularly sub-Saharan Africa, exhibits high levels of morbidity and mortality associated with diarrhea, acute respiratory infection, and malaria. With the increasing awareness that the aforementioned infectious diseases impose an enormous burden on developing countries, public health programs therein could benefit from parsimonious general-purpose for...
