Oxygen is an important element for plant growth.Reducing its concentration in the soil affects physiological processes such as nutrient and water uptake well respiration, redox potential of elements activity microorganisms.The main mechanism oxygen transport by diffusion, a dynamic process greatly influenced physical properties texture structure, conditioning, pore size distribution, tortuosity connectivity.Organic matter modifying agent soil's chemical properties, affecting structure porous...

BACKGROUND: Experimental evidence to disprove the belief that emergency contraception with levonorgestrel (LNG) prevents pregnancy by interfering post‐fertilization events is lacking. Here we determined effect of post‐coital and pre‐ovulatory administration LNG on fertility ovulation, respectively, in Cebus monkey. METHODS: To determine fertility, 0.75 mg or vehicle were administered orally s.c. once twice within first 24 h after mating occurring very close time ovulation. Females became...

The current global agricultural challenges imply the need to generate new technologies and farming systems.In this context, rootstocks are an essential component in modern agriculture.Most currently used those clonally propagated there several ongoing efforts develop type of plant material.Despite tendency, lesser number rootstock breeding programs exists comparison large for scion cultivars.In case rootstocks, traits evaluated selection lines quite different: From agronomic standpoint vigor...

Under transient waterlogging, a number of transformations in the soil are generated associated with lack aeration, seriously affecting root system.Significant progress has been reported on understanding effects oxygen metabolism roots, although few studies have examined changes soil.Diverging conclusions about degree tolerance exhibited by plants exclude hypoxia and anoxia physical-chemical properties under plant experiments.This review examines main occurring roots due to waterlogging...

As it approaches the maternal surface, attaching embryo encounters epithelial glycocalyx, which contains mucin, MUC1. A high density of MUC1 at cell surface can inhibit adhesion. This raises possibility existence a uterine barrier to implantation that might allow rejection poorer quality embryos. To investigate mechanism implantation, human embryos were incubated with endometrial monolayers. Hatched blastocysts found attach readily surface. was lost from cells beneath and near attached...

To determine if the egg provides any clues for regulation of ovum transport in hamster, oocyte and embryo were compared. On evening preceding ovulation, animals randomly assigned to one five groups. They caged overnight with a male proven fertility (Group 1) or they isolated 2). Other females artificially inseminated both uterine horns at 2200 h either fertile epididymal spermatozoa 3), rendered infertile by freezing thawing 4), horn contralateral 5). The number, condition, distribution ova...

The effects of water availability were evaluated on the photosynthetic tissue anatomy in Aloe vera (L) Burm f. and its relationship with morphological, physiological parameters, use efficiency as a function aerial biomass gel production. Plants subjected to four levels equivalent 20% (T1), 15% (T2), 10% (T3), 5% (T4) atmospheric evaporative demand. plants exhibited anatomical, responses different watering treatments. extreme treatments produced negative due excess T1 deficit T4. Treatments...

The HPLC-DAD analysis identified eight phenolic compounds in the leaf and fruit pulp of Randia echinocarpa, highlighting chlorogenic acid with highest concentration, followed by ferulic rutin. Previous analyses have reported similar profiles R. echinocarpa other species same genus, such as monantha, where rutin were predominant compounds. concentration total phenolics was found to vary depending on plant tissue season, being during autumn lowest bark winter. In present study it is for first...

This paper presents the design, implementation, and testing of a traffic monitoring platform based on 5G-connected Ultra-Wideband (UWB) radars deployed university campus. The development both connected an IoT is detailed. integrate commercial components, including Raspberry Pi (RPi), UWB radar, standard enclosure, custom communication board featuring 5G module. platform, which receives data from via MQTT, scalable, easily deployable, supports radar management, visualization, external access...

A possible role of the quality eggs in regulation ovum transport was investigated pseudopregnant rats. Pseudopregnancy induced by mechanical stimulation cervix at 2200 h on day proestrus. This immediately followed artificial insemination with fertile or infertile epididymal spermatozoa. The following designated as Day 1 pseudopregnancy. Spermatozoa were rendered freezing and thawing. Insemination spermatozoa yielded between 80% 100% normally developing embryos, judged their microscopic...

The effect of the inhibition nitric oxide synthase (NOS) on ovum transport and oviductal motility in rats was investigated. Three different NOS inhibitors were injected into ovarian bursa at oestrus or day 3 pregnancy. Oviducts uteri flushed 24 h later presence ova recorded. In oestrous pregnant rats, treatment resulted accelerated egg transport, as shown by a decrease number present oviducts. cyclic intrabursal injection 1 mg kg-1 either N-monomethyl-L-arginine (L-NMMA) N omega...

Indirect evidence of embryo signalling to the oviduct was sought in rats by examining transport embryos different ages. One-cell or four-cell were transferred oviducts recipient on Day 1 pregnancy, and number, condition, location native assessed 4. To control for effect presence foreign excess number eggs transfer procedure upon fate embryos, other groups sham-operated left undisturbed. Recipients had a mean ova significantly higher than controls. In controls recipients 1-cell majority...

The hyper-arid Atacama Desert is one of the most extreme environments for life and only few species have evolved to survive its aridness. One such tree Prosopis tamarugo Phil. Because Tamarugo completely depends on groundwater, it being threatened by high water demand from Chilean mining industry human consumption. In this paper, we identified important biophysical variables assess status trees tested potential WorldView2 satellite images retrieve these variables. We propose green canopy...

The co-expression of alpha1beta1, alpha4beta1 and alphavbeta3 integrins in the human endometrium coincides with implantation window. integrin is expressed apical surface luminal epithelium may serve to anchor trophoblast cells adhesion phase implantation. Using immunohistochemistry, we compared expression alphav, alpha1, alpha4 beta3 subunits samples normal Fallopian tube obtained from five women non-receptive period (luteal days 2-4) another receptive 6-8). staining was quantified visually...

Abstract Few reports on the reproductive physiology of Cebus apella have been published. In this study we characterized menstrual cycle events by means vaginal cytology, ultrasonography (US), and hormonal measurements in serum during three consecutive cycles 10 females, assessed probability that ovulation would occur same ovary 18 females. The lengths phases were determined according to cytology. Taking first day endometrial bleeding as cycle, mean length ± SEM was 19.5±0.4 days, with...

Abstract Two oocytes recovered from the Fallopian tube at 24 and 50 h following LH peak in plasma were examined by light microscopy transmission electron microscopy. The possibility of fertilization was excluded clinical morphologic evidence. In earliest specimen, first polar body showed condensed nuclear chromatin, without envelope, is interpreted as entering interphase. other undergoing division, which spontaneous second meiotic division.
