Iatrogenic botulism resulting from the substantial increase in use of botulinum neurotoxin type-A (BoNT-A) treatment is rarely reported. We aimed to describe a large iatrogenic botulism outbreak in Egypt in June-July 2017. Nine patients developed botulism after receiving intramuscular injections of BoNT-A (dose: 200-300 IU) to treat cerebral palsy (N=7), spastic dystonia (N=1), and hyperhidrosis (N=1). Detailed findings were available in 5/9 cases. Patients were admitted to the hospital 5-10 days after the BoNT-A injection...

Rapid and accurate identification of endangered species is a critical component of bio-surveillance and conservation management, and potentially policing illegal trades. However, this is often not possible using traditional taxonomy, especially where only small or pre-processed parts of plants are available. Reliable identification can be achieved via a comprehensive DNA barcode reference library, accompanied by precise distribution data. However, these require extensive sampling at spatial and taxonomic scales, which has rarely been achieved for cosmopolitan taxa...

Acute generalized exanthematous pustulosis is a rare adverse cutaneous reaction characterized by the rapid appearance of numerous pustules arising on edematous, erythematous skin. It is commonly accompanied by fever and leukocytosis and usually resolves with discontinuation of the offending agent. Herein, acute generalized exanthematous pustulosis induced by terbinafine is described, followed by a brief review of the literature.

Ferroelectric materials exhibit switchable remanent polarization due to reversible symmetry breaking under an applied electric field. Previous research has leveraged temperature-induced neutral-ionic transitions in charge-transfer (CT) cocrystals to access ferroelectrics that operate through displacement of molecules under an applied field. However, displacive ferroelectric behavior is rare in organic CT cocrystals and achieving a Curie temperature (TC) above ambient has been elusive. Here a cocrystal between acenaphthene and 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane is presented that shows switchable remanent polarization at room temperature (TC = 68°C)...

Although oxidative addition (O.A.) and reductive elimination (R.E.) are exceedingly important processes in organometallic chemistry, such processes are still extremely rare for main group element species. Here we report a theoretical study on the reaction of phosphine-stabilized silylenes with silanes which proceeds via reversible O.A./R.E. at room temperature. Of particular interest, this theoretical approach highlights the important role of the ligand, which can greatly affect kinetics and energy balance of the reaction...

Linking intraspecific and interspecific divergence is an important challenge in speciation research. X chromosomes are expected to evolve faster than autosomes and disproportionately contribute to reproductive barriers, and comparing genetic variation on X and autosomal markers within and between species can elucidate evolutionary processes that shape genome variation. We performed RADseq on a 16-population transect of two closely-related Australian cricket species, Teleogryllus commodus and T. oceanicus, covering allopatry and sympatry...

BACKGROUND: Most patients with anemia are diagnosed through clinical phenotype and basic laboratory testing. Nonetheless, in cases of rare congenital anemias, some patients remain undiagnosed despite undergoing an exhaustive workup. Genetic testing is complicated by the large number of genes involved in rare anemias and the similarities in the clinical presentation of the different syndromes. OBJECTIVE: We aimed to enhance the diagnosis of patients with congenital anemias by using targeted next-generation sequencing...

Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML). All-trans retinoic acid (ATRA) is the first-choice therapy for the treatment of this disease, but has been associated with side effects, the most serious of which is retinoic acid syndrome (RAS). RAS is characterized by unexplained fever, dyspnea, pulmonary infiltrate, leukocytosis and nephropathy. Genital ulcers have been described in some cases, but only two cases of oral ulcers related to this syndrome have been described in the literature...

There is a widespread myth that we have to be careful about what we eat so that we do not cause protein deficiency. We know today that it is virtually impossible to design a calorie-sufficient diet, whether it is based on meat, fish, eggs, various vegetarian diets or even unprocessed whole natural plant foods, which is lacking in protein and any of the amino acids. The body is capable of taking incomplete proteins and making them complete by utilizing the amino acid recycling mechanism. The majority of amino acids absorbed from the intestinal tract are derived from recycled body protein...

Stipa pennata (Poaceae), has become a rare and endangered species in Central Europe due habitat loss and fragmentation. This species is characterized by high morphological variability, which has resulted in the description of numerous intraspecific taxa. The aim of present work is to develop microsatellite markers useful in population genetics studies as well as in intraspecific taxonomy of S. pennata s.l. We developed ten microsatellite markers using Illumina high-throughput. Polymorphism at each marker was evaluated using 4-15 individuals from four morphotypes of S...

Spontaneous ion separation of the scorpionate beryllium complex, TpBeI 1 (Tp = 1-trispyrazolylborate), occurs upon treatment with THF, yielding [TpBe(thf)]I 2, which was characterized by heteronuclear NMR spectroscopy (1H, 9Be, 13C) and structurally characterized by single crystal X-ray diffraction. 2 represents a rare example of a structurally characterized monocationic beryllium complex, and to the best of our knowledge, the synthesis of 2 by a solvent-induced ion separation has previously only been observed in the reactions of beryllium dihalides with strong Lewis bases...

Highly active and durable electrocatalysts for the hydrogen evolution reaction (HER) may play a pivotal role in commercial success of electrolytic water splitting technology. Among various material classes, binary metal sulphides show a great promise as HER catalysts because of their tunable energy levels conducive to a high catalytic activity and high robustness under harsh operating conditions. On the other hand, facet-controlled nanoparticles with controlled surface energies have gained great recent popularity as active and selective catalysts...

As primary duodenal adenocarcinoma is rare, the prognostic factors of this disease remain insufficiently explored, especially in China. We identified postoperative duodenal adenocarcinoma patients at a Chinese double-center (from 2006 to 2016) or who were registered with the Surveillance, Epidemiology, and End Results (SEER) database (from 2004 to 2014). Clinicopathological features and significant prognostic factors for cancer-specific survival (CSS) were reviewed and analyzed by using univariate and multivariate Cox proportional hazards regression...

Eight new 4-hydroxy-2-pyridone alkaloids arthpyrones D⁻K ( 1 ⁻ 8 ), along with two known analogues apiosporamide ( 9 ) and arthpyrone B ( 10 ), were isolated from a deep-sea-derived fungus Arthrinium sp. UJNMF0008. The structures of the isolated compounds were elucidated on the basis of spectroscopic methods with that of 1 being established by chemical transformation and X-ray diffraction analysis. Compounds 1 and 2 bore an ester functionality linking the pyridone and decalin moieties first reported in this class of metabolites, while 3 and 4 incorporated a rare natural hexa- or tetrahydrobenzofuro[3,2- c ]pyridin-3(2 H )-one motif...

OBJECTIVE: Adult granulosa cell tumor (AGCT) is a rare form of sex-cord stromal ovarian tumors. Due to their origin, AGCTs secrete estrogens, and thus, estrogen receptor (ER)-mediated signaling has been considered as a possible target for therapy. The aim of the present study was to get insights into estrogen receptor status and activity in AGCTs, as a strategy to provide molecular support for personalized hormonal treatments. METHODS: We evaluated by immunohistochemistry the expression of ERα, ERβ isoforms (i...

In the Iberian Peninsula, Miocene apes (Hominoidea) are generally rare and mostly restricted to the Vallès-Penedès Basin. Here we report a new hominoid maxillary fragment with M2 from this basin. It was surface-collected in March 2017 from the site of Can Pallars i Llobateres (CPL, Sant Quirze del Vallès), where fossil apes had not been previously recorded. The locality of provenance (CPL-M), which has delivered no further fossil remains, is located very close (ca. 50 m) to previously known CPL outcrops, and not very far (ca...
