BACKGROUND Subfertility affects one in eight couples. In up to 50% of cases, the male partner has low semen quality. Four Y chromosome deletions, i.e. Azoospermia factor a (AZFa), P5/proximal-P1 (AZFb), P5/distal-P1 and AZFc deletions, are established causes of low semen quality. Whether a recently identified partial AZFc deletion, the gr/gr deletion, also causes low semen quality is at present...

Abstract Orthoptera have some of the largest genomes all insects. At same time, architecture their remains poorly understood. Comparative cytological data across a wide range taxa, even for basic parameters such as chromosome number, may provide important insights into evolution these and help answer question why species attained large genome sizes. We collected compiled more than 1,000 records...

The forage palm is widely cultivated in semiarid regions. It has a basic chromosome number of x = 11 and polyploids are the main variation. propagated via vegetative reproduction, sexual propagation rarely used. objective was to associate physiological quality seeds different cultivars with level ploidy genera Opuntia Nopalea. used were: diploids (2n 22) ‘F8’, ‘F21’, ‘IPA Sertânia’; tetraploids...

Introduction: Although Acute Myeloid Leukemia (AML) has been associated with several environmental factors, in some patients the evolution to AML is preceded by myelodysplastic syndrome (MDS). We report a case of 63-year-old male who was diagnosed sporadic monosomy 7 MDS/AML achieved good response treatment CPX-351 (Vyxeos) induction chemotherapy. Case information: A initially presented ED for ...

There have been many reports of cases in which chronic increases in the numbers of natural killer (NK) cells have been reported. Whether this is reactive or neoplastic in nature has been debated. We report the first case of an aggressive NK cell leukemia in an adult with establishment of an NK cell line. A 70-year-old man had two spontaneous episodes of jejunal perforation and one month later d...

Isoetes mississippiensis S.W. Leonard, W.C. Taylor, L.J. Musselman and R.D. Bray (Isoetaceae, Lycopodiophyta) is a new species known from two sites along tributaries of the Pearl River in southern Mississippi. This species is distinguished from other species in the southeastern United States by a combination of character states including a basic diploid (2n=22) chromosome count, laevigate megas...
