Patterned hair loss (PHL) is one of the most commonly encountered problems for dermatologists. PHL at an early age is often cosmetically unacceptable, tends to be persistent and inflicts a profound negative impact on one’s quality of life. Androgenetic alopecia (AGA) affects both genders in a distinctive pattern of hair loss from the scalp (MPHL for male PHL and FPHL or female PHL). The etiopat...

The emergence of Covid-19 has deeply disturbed the aviation industry in many aspects. This study examines effect on departure delay time and flight cancellation at Philadelphia International Airport (PHL). By analyzing data nearly 200,000 flights departed from PHL between January 2019 February 2021, research found that noticeably reduced time, cancellations sharply rose then quickly dropped. Fu...

The growing demand for rayon and cellulosic products has resulted in the conversion of a number of kraft pulp mills into dissolving pulp mills in recent years. In fact, kraft-based dissolving pulp production fits well into the concept of an integrated forest biorefinery, in particular, the utilization of dissolved organics in the pre-hydrolysis liquor (PHL) for bio-materials and bio-energy purp...

One problem of conventional allergen-specific immunotherapy is the risk of anaphylactic reactions. A new approach to make immunotherapy safer and more efficient might be the application of engineered allergens with reduced IgE-binding capacity but retained T cell reactivity. Using overlapping dodeca-peptides, the dominant T cell epitopes of the timothy grass pollen allergen Phl p 5b were identi...

A ROSAT observation of the narrow-line Fe II QSO PHL 1092 shows rapid variability that requires an efficiency of at least 0.13, exceeding the theoretical maximum for an accretion disk around a non-rotating black hole. Plausible explanations for this high efficiency incorporate anisotropic emission and/or accretion onto a rapidly rotating black hole, the latter recently suggested by Kwan et al. ...

More than 10% of the population in Europe and North America suffer from IgE-associated allergy to grass pollen. In this article, we describe the development of a vaccine for grass pollen allergen-specific immunotherapy based on two recombinant hypoallergenic mosaic molecules, designated P and Q, which were constructed out of elements derived from the four major timothy grass pollen allergens: P...

On June 27, 2016, the Minnesota Department of Health (MDH) Public Health Laboratory (PHL) was notified of a suspected Francisella tularensis isolate cultured at a hospital laboratory. The isolate was confirmed as F. tularensis type B at MDH PHL by reverse transcription-polymerase chain reaction, culture, and direct fluorescent antibody testing. Francisella tularensis subspecies tularensis (type...

▼ Nodular lymphocyte-predominant Hodgkin lymphoma (nLPHL) is a very rare disease in childhood and adolescence. In Germany, about 15 newly diagnosed patients present with this disease annually; this number comprises less than 10 % of all pediatric Hodgkin lymphoma cases. Since the EuroNet-PHL-LP1 trial for early stage nLPHL patients stopped recruiting in Germany in October 2014, the GPOH-HD writ...

HST images (with WFPC2) of PHL 909 (z = 0.171) and PG 0052+251 (z = 0.155) show that these luminous radio-quiet quasars each occur in an apparently normal host galaxy. The host galaxy of PHL 909 is an elliptical galaxy (∼ E4) and the host of PG 0052+251 is a spiral (∼ Sb). Both host galaxies are several tenths of a magnitude brighter than L, the characteristic Schechter luminosity of field gala...
