Polycystic liver disease (PLD) is characterized by the presence of multiple bile duct-derived epithelial cysts scattered in the liver parenchyma. PLD can manifest itself in patients with severe autosomal dominant polycystic kidney disease (ADPKD). Isolated autosomal dominant polycystic liver disease (ADPLD) is genetically distinct from PLD associated with ADPKD, although it may have similar pathogenesis and clinical ***, mutations in two causative genes for ADPLD,independently from ADPKD, have been identified. We report here a family (a mother and her daughter) with a severe form of ADPLD not associated with ADPKD produced by a novel missense protein kinase C substrate 80K-H (PRKCSH) mutation (R281W). This mutation causes a severe phenotype, since the two affected subjects manifested signs of portal hypertension. Doppler sonography, computed tomography (CT) and magnetic resonance (MR) imaging are effective in documenting the underlying lesions in a non-invasive way.

Isolation and Characterization of 26 Microsatellite Loci for the Shortfin Silverside Fish <i>Chirostoma humboldtianum</i>Valenciennes1835 (Atherinopsidae: Menidiinae) Derived from next Generation Sequencing and Their Cross-Amplification in Central Mexican Atherinopsids

The endemic silverside fish C. humboldtianum is of great ichtyologycal, economical and cultural relevance in central Mexico and it has been suggested that it is among a group of other “peces blancos”, the most ancestral species. Here we characterized a set of 26 microsatellite loci from the species in order to further assess population and phylogeographic issues that aid in evaluating their highly impacted populations. From 58 primer pairs tested on specimens from Villa Victoria dam (Rio Balsas Basin), 26 loci positively amplified on the species and cross-primed on specimens of the closely related and threatened Poblana alchichica, C. promelas and C. riojai. Loci resolved medium and high genetic variation (mean nA = 14.3, SD = 9.38;mean HO & HE = 0.47, SD = 0.32 and 0.58, SD = 0.32, respectively) and it is expected that these polymorphic loci are also useful in studing threatened atherinopsid species.

Dominant Macroalgae in Bahía de Cochinos, Matanzas, Cuba

American Journal of Plant Sciences 2022年第6期13卷 797-814页

Spatial-temporal variations of macroalgae were analyzed in a study conducted in Cueva de Los peces (CP) and Punta Perdiz (PP), two dive sites located on the eastern coast of Bahía de Cochinos. The most conspicuous species found from 3 to 20 m depths were present in the biotopes of ridges and shallow and deep terraces. Sampling was carried out in September 2014, and March and October 2016 by autonomous diving and direct methods. Qualitative visual censuses and quantitative analyzes were used to estimate the coverage (%) of the genera according to the AGRRA methodology with the use of the 10 m linear transect and quadrats as the sampling unit. The first list of macroalgae for the area is offered that includes 49 taxa of which 10 were Rhodophyta, 10 Ochrophyta (Phaeophyceae), and 29 Chlorophyta. The dominant genera during the study period were Halimeda, Dictyota, Lobophora, and Udotea. Spatial differences were found regarding the specific composition. Temporal variations were evidenced in terms of the relative abundance of the genera present, which reveals temporal changes in the qualitative structure, where some species replace others. The information obtained is pioneering and can serve as a comparative baseline for future monitoring of the area.
