Multi-loci phylogeny and morphological evidence support the recognition of Januaria (Spermacoceae, Rubiaceae), a new monospecific genus endemic to the North of Minas Gerais (Brazil).

Januaria is described as a new monospecific genus of Rubiaceae, based on material from Januária, northern Minas Gerais, Brazil. The new taxon is endemic to Brazil, occurring in a vegetation type that is known locally as "carrasco", in the southern limit of the Caatinga biome. Morphological (including palynological and SEM analyses) and molecular phylogenetic analyses based on nuclear (ETS, ITS) and plastid (atpB-rbcL, peth, rps16, trnL-trnF) sequence data were performed in the Spermacoce clade (tribe Spermacoceae).

Anther structure and pollen development in species of Rubiaceae and anatomical evidence of pathway to morphological dioecy.

we conducted anatomical analysis of anthers with the aim to establish the differences in the development pattern of microsporophytes and microgametophytes between perfect and imperfect flowers in the tribe Gardenieae (Rubiaceae). The species studied were: Tocoyena formosa (monoecious with perfect flowers), Cordiera concolor, Genipa americana, Randia calycina, and Randia heteromera (dioecious with imperfect flowers). Flowers in successive stages of development were collected and fixed.

Colleters in Cephalanthus (Rubiaceae) and reevaluation of occurrence of corolline colleters in Angiosperms.

Colleters are glandular structures related to young shoots protection. In several Angiosperm families, as in Rubiaceae colleters are taxonomically important. This study reports presence, location, morpho-anatomical structure, ontogeny and histochemistry of colleters in vegetative and reproductive organs in 6 species of Cephalanthus and 20 species representatives of the tribe Naucleeae.

Anatomy and development of the edible fruits of Cordiera concolor (Rubiaceae).

A comprehensive study on the fruit anatomy and development of Cordiera concolor was carried out to establish the origin of the gelatinous tissue surrounding the seeds at maturity. Cordiera currently belongs to tribe Cordiereae, forming part of the species-rich lineage called Gardenieae complex. Most genera of Gardenieae complex has many-seeded fleshy fruits, with seeds usually imbedded in a pulp, which historically was considered of a placental nature.

Embryology of some flowers of the Gardenieae complex (Rubiaceae).

Different breeding systems occur in the Gardenieae complex (Rubiaceae), from homoecy to dioecy which is present in two tribes, Gardenieae and Cordiereae. As part of a broad project focused on the reproductive anatomy of the species of these two tribes, we described the structural and functional differences of the gynoecium in the different floral morphs and determined the degree of gynoecium development in the staminate flowers. We conducted a comparative anatomical study focused on the gynoecium of one homoecious species (Tocoyena formosa, with perfect flowers) and three dioecious species (Genipa americana, Randia calycina, and Randia heteromera) of Gardenieae and one dioecious species (Cordiera concolor) of Cordiereae.

[Strategies to advance recovery (STAR) protocol implemented colorectal cancer patients during the COVID-19 pandemic].

Background: SARS-CoV-2 hampered the resolution of multiple diseases, including cancer.

Aim: To show that a multidisciplinary program of Strategies to Advance Recovery (STAR) can be implemented in a public hospital in Chile, despite the global pandemic and state of a national catastrophe, to provide a solution to cancer patients.

Material And Methods: A retrospective descriptive study, of patients requiring an elective resolution of a colorectal cancer.

Floral anatomy, embryology, seed, and fruit development in Cephalanthus (Naucleeae-Rubiaceae), with emphasis on C. glabratus.

Information on the reproductive anatomy in genera of the tribe Naucleeae, particularly Cephalanthus, is scarce and fragmented. Of the six species in the genus, only the mature megagamethophyte of Cephalanthus occidentalis has been described. This study aims to provide information on embryological aspects in flowers of C.

Androecium anatomy of Isertia laevis, a polysporangiate species of Rubiaceae.

In this study, we performed an anatomical analysis of the polysporangiate anthers and the development of pollen in Isertia laevis (Rubiaceae) with the aim to elucidate the internal structure of these atypical anthers. For this purpose, flowers in successive stages of development were dissected and the anthers were processed for conventional anatomical analysis. The material was examined using light microscopy and scanning electron microscopy.

Morphological and molecular data confirm the transfer of homostylous species in the typically distylous genus (Rubiaceae), and the description of the new species from Peru and Colombia.

(Rubiaceae) is a neotropical genus comprising 50 species divided into two subgenera, subgen. with 39 species and subgen. , with 11 species.

Plasminogen activator inhibitor type 1 serum levels and 4G/5G gene polymorphism in morbidly obese Hispanic patients with non-alcoholic fatty liver disease.

Background: The plasminogen activator inhibitor type-1 (PAI-1) has been implicated in the regulation of fibrinolysis and extracellular matrix components. The single base pair guanine insertion/deletion polymorphism (4G/5G) within the promoter region of the PAI-1 gene influences PAI-1 synthesis and may modulate hepatic fibrogenesis.

Aim: To evaluate the influence of PAI-1 serum levels and 4G/5G polymorphism on the risk of liver fibrosis associated to non-alcoholic fatty liver disease (NAFLD) in morbidly obese patients.
