The three-dimensional ultrastructure of over 1000 mitochondria in human Leydig cells (from twelve sexually mature patients) was examined by high resolution scanning electron microscopy (HRSEM) of osmium-macerated specimens, as well as by transmission electron microscopy of conventional ultrathin sections. The stereo-pair imaging of the osmium-macerated specimens by HRSEM is also very useful for...

The origin and processes creating the high diversity of plant species in neotropical rain forests and their floristic composition and multistratitified forest structure are still uncertain. Here, we studied one of the most common leaf morphotypes of the Cerrejón flora (middle-late Paleocene, ca. 60-58 Ma), Guajira, Colombia, that contains one of the oldest records of neotropical rain forest flo...

A new therocephalian specimen collected from the upper part of the Ermaying Formation of Liulin, Shanxi, China is named as Nothogomphodon sanjiaoensis sp. nov. This new species is differentiated from the type species Nothogomphodon danilovi by the following characters: dentary lower margin uneven; canine base is ovate rather than rounded; distinct diastema present between canine and first postc...

A green mold species that has not previously been reported in Korea was isolated from oak log beds used for shiitake (Lentinula edodes) cultivation that were infested by mushroom flies. In this study, we identify the mold species as Gliocladium viride (an anamorph of Hypocrea lutea) and describe its mycological properties. The fungus was cottony on both potato dextrose agar (PDA) and Czapek yea...

Some interesting Bupleurum (Apiaceae) specimens with very branched stems, (1–)2-rayed inflorescences and ivory-white bracteoles were collected from Tepebaşı District (Eskişehir Province). The specimes, at first glance, resembled the pendikum (sect. Aristata) species, which is endemic in Türkiye, as a habit. However, result of detailed examination, it was determined that there some differences. ...

The experiment was performed at Maharajpur Farm under the Department of Horticulture, College Agriculture, J.N.K.V.V., Jabalpur (M.P.) during Kharif season 2019-2022 and planted in Randomized Complete Block Design (RCBD) with three replications. characterization thirty genotype for thirty-five qualitative traits articulated no variability trait i.e., monomorphic non-enveloping fruit calyx cover...

Distinctness, Uniformity, and Stability (DUS) characterization of ninety recently evolved soybean genotypes including three national checks were carried out at JNKVV, Jabalpur, during Kharif 2021. Sixteen DUS traits evaluated as described by National test guidelines. Observations made on Hypocotyl Pigmentation, Growth type, habitat, Leaf shape, size, colour, Flower Pod hairiness, pub intensity ...

the allelopathic effect of weeds frequently inhibited the germination and seedling growth of crops. johnsongrass (sorghum halepens) is known to contain water-soluble substances that are allelopathic. to identify the allelopathic effect of johnsongrass, the effect of different aqueous extracts (0, 5, 10, 20, 30, 40 and 50 g l-1) obtained from roots and leaves of johnsongrass on the seed germinat...
