The human kallikrein (KLK)-related peptidases are the largest family of serine peptidases, comprising 15 members (KLK1-15) and with majority (KLK4-15) being identified only within last decade. Members this associated important diseased states (including cancer, inflammation, neurodegeneration) have been utilized or proposed as clinically biomarkers therapeutic targets interest. All KLKs synthesized prepro-forms that proteolytically processed to secreted pro-forms via removal an...
A new species of Acanthocereus, endemic from southern Jalisco, is described and illustrated. Acanthocereus atropurpureus distinguishes by the diameter mature stems, presence low ribs with sinuate margins, dull green stem epidermis turning purple during dry season, occurrence four small central spines. We discuss morphological differences other we provide information about its habitat conservation status.
Societal Impact Statement Crop wild relatives (CWR) are plant taxa closely related to crops and a source of high genetic diversity that can help adapt the impacts global change, particularly meet increasing consumer demand in face climate crisis. CWR provide vital ecosystem services increasingly important for food nutrition security sustainable resilient agriculture. They therefore major biological, social, cultural economic importance. Assessing extinction risk is essential prioritise situ...
The current infrafamilial taxonomy of the Iridaceae recognizes four subfamilies; Isophysidoideae (1: 1); Nivenioideae (6: ca. 92), Iridoideae (29: 890), and Crocoideae 1032). Phylogenetic analyses sequences five plastid DNA regions, rbcL , rps4 trnL–F matK rps16 confirm most aspects this classification evolutionary patterns that they imply, importantly sisiter relationship to remainder family monophyly Iridoideae. Subfamily is, however, paraphyletic; is consistently found nested within it,...
Solanum section Petota, the potato and its wild relatives, contains about 200 species distributed from southwestern United States, to central Argentina adjacent Chile. Although most occur in South America, a secondary center of diversity peaks at 20 degrees north Mexican highlands, including diploids (2n = 2x 24), tetraploids 4x 48), hexaploids 6x 72), triploid pentaploid nothospecies. This treatment covers potatoes North Central America (United States Panama). It is summary recent...
Abstract Crop wild relatives (CWR) intra- and interspecific diversity is essential for crop breeding food security. However, intraspecific genetic diversity, which central given the idiosyncratic threats to species in landscapes, usually not considered planning frameworks. Here, we introduce an approach develop proxies of differentiation identify conservation areas, applying systematic tools that produce hierarchical prioritizations landscape. It accounts for: (i) evolutionary processes,...
Background: Acute intracranial stenting for the treatment of patients with large vessel occlusion in case failed reperfusion or severe stenosis is a growing practice. Our aim was to explore clinical and radiological outcome multicenter international registry. Methods: The RESISTANT registry retrospective stroke that underwent due an acute from 2016 2023. Primary endpoints at 90 days. Secondary efficacy were final (mTICI 2b-3), stent patency 24 hours. Safety outcomes included procedural...
Background: Intracranial stenting is increasingly performed after thrombectomy failure. Stent selection and procedural strategies are heterogenous between centers. Our aim to evaluate the clinical radiological impact of stent design among these patients. Methods: The RESISTANT registry a multicenter, international, retrospective study patients with acute ischemic stroke who underwent intracranial from 2016 2023. This analysis compares outcomes based on type evaluates role pre- post-stenting...
Background: Previous studies suggest that in patients who fail to recanalize with devices approved for mechanical thrombectomy, early bailout intracranial stenting might lead better outcomes. We aimed investigate weather the number of previous failed thrombectomy attempts (FTA) impacts outcomes after stenting. Methods: The RESISTANT registry is a multicenter and international retrospective large vessel occlusion stroke presenting within 24 hours symptom onset underwent due an acute from 2016...
Onagraceae are a family of 17 genera in seven tribes, with the majority species tribes Onagreae and Epilobieae. Despite species-richness these two to date no phylogenetic study has been done sufe cient taxon sampling examine relationships between within tribes. In this study, we used DNA sequence data from one nuclear region (ITS) chloroplast regions ( trnL-trnF rps16) infer among93taxa across thefamily, withconcentratedsamplinginthelargetribeOnagreae.Results...
Background: Knowledge on Mexican Solanaceae is uneven. Several areas are well collected and have been floristically treated in recent times, but others neglected poorly represented herbaria.
 Question: Which species of grow Mexico which their state distribution.
 Study site: from 2009 to 2011.
 Methods: We reviewed family literature as North American herbaria. analyzed distribution for each state, endemism the country MegaMexico.
 Results: found three subfamilies...

Abstract Mexico is a megadiverse country. Presently, 22 126 species of angiosperms have been registered within its territory and 11 001 are considered to be endemic. However, their geographical distributions far from homogeneous. In addition, the center diversification several groups. Our analysis focused on such The aims were identify areas richness endemism. A data matrix with 766 25 579 records was analyzed. It included Calochortus (Liliaceae); Bletia (Orchidaceae); Tigridieae...

The genus Psilocybe contains iconic species of fungi renowned for their hallucinogenic properties. Recently, also included non-hallucinogenic that have since been shifted to the Deconica. Here, we reconstruct a multigene phylogeny Psilocybe, Deconica, and other exemplars families Hymenogastraceae Strophariaceae sensu stricto (s. str.), using three nuclear markers (nLSU-rRNA, 5.8S rRNA, rpb1). Our results confirm monophyly Deconica within s. str., as well numerous robust infrageneric...
The tribe Tigridieae (Iridoideae: Iridaceae) is a New World group with centres of diversity in Mexico and Andean South America. North America harbours 67 the 172 species recognised within tribe, 54 being endemic. Our aims were to identify areas endemism American using endemicity analysis (EA) infer their relationships parsimony (PAE). A data matrix 2769 geographical records was analysed. EA allowed six consensus Mexico. PAE resulted one cladogram four clades following five biotic components:...
Abstract Native Mexican woody bamboos (Poaceae: Bambusoideae: Bambuseae) are classified in subtribes Arthrostylidiinae, Chusqueinae and Guaduinae. They grow from sea level up to 3200 m along the main mountain ranges occupy different vegetation types. The aims of this study were to: identify areas with most species diversity; detect endemism; discuss conservation status native bamboos. We gathered presence records for 51 bamboo species, based on herbarium personal collections. Richness was...
Gypsum soils occur around the world, mainly in arid regions. These harsh environments promote unusual flora with high degrees of endemism. Mexico has extensive gypsum outcrops, but their been poorly studied. However, highest species richness and endemism are expected to be concentrated Mexico’s northern dry To study this its conservation, we estimate how well sampled it is, quantify richness, identify centers endemism, detect which outcrops lie within federal protected natural areas (PNA)....
