Abstract:

The intake of a fructose-rich diet (FRD) in the normal female rat induces features similar to those observed in the human metabolic syndrome phenotype. We studied the impact of FRD administration to mothers on pregnancy outcome. On gestational day (Gd) zero rats were assigned to either group: ad libitum drinking tap water alone (normal diet, ND) or containing fructose (10% w/vol; FRD) through pregnancy; all rats were fed a Purina chow diet ad libitum ND and FRD rats were daily cotreated or not with metformin (60 mg/Kg/day oral; ND + MF and FRD + MF) and submitted to a high glucose load test on

In the present study, we tested the effect of OS (oxidative stress) inhibition in rats fed on an FRD [fructose-rich diet; 10% (w/v) in drinking water] for 3 weeks. Normal adult male rats received a standard CD (commercial diet) or an FRD without or with an inhibitor of NADPH oxidase, APO (apocynin; 5 mM in drinking water; CD-APO and FRD-APO).

Abstract:

We analyzed the effect of naringin (NAR), a flavonoid from citric fruits, on bone quality and biomechanical properties, as well as the redox state of bone marrow in rats fed a fructose-rich diet (FRD), an experimental model to mimic human metabolic syndrome. NAR blocked the increase in the number of osteoclasts and adipocytes and the decrease in the number of osteocytes and osteocalcin (+) cells caused by FRD. Trabecular number was significantly higher in the FRD+NAR group. FRD induced a decrease in the femoral trabecular and cortical bone mineral density, which was blocked by NAR. The fractur

Abstract:

ABSTRACT Fumarate reductase (FRD) is an enzyme that reduces fumarate to succinate. In many organisms, it is bound to the membrane and uses electron donors such as quinol. In this study, an FRD from a thermophilic chemolithoautotrophic bacterium, Hydrogenobacter thermophilus TK-6, was purified and characterized. FRD activity using NADH as an electron donor was not detected in the membrane fraction but was found in the soluble fraction. The purified enzyme was demonstrated to be a novel type of FRD, consisting of five subunits. One subunit showed high sequence identity to the catalytic subunits

The adipose tissue renin–angiotensin system (RAS) is proposed to be a pathophysiological link between adipose tissue dysregulation and metabolic disorders induced by a fructose-rich diet (FRD).

Favre–Racouchot disease (FRD) is clinically characterized by the presence of open comedones, small papules, and cystic lesions with deep wrinkles and furrows on sun-exposed areas, especially the face. FRD is a purely cosmetic disorder, with most patients not requesting treatment. Dermoscopy may play a vital role in diagnosing early lesions of FRD, averting the need for an invasive procedure such as a skin biopsy, and helping to differentiate it from close mimics. The dermoscopic features of FRD have not been reported in the literature before. We report a clinicoepidemiological profile and derm

Different silvicultural treatments that are applied at plantation establishment may drive different vegetation succession pathways.

Abstract:

Environments with a low red (R, 600 to 700 nm) to far-red (FR, 700 to 800 nm) ratio (e.g., with high plant density) promote stem elongation, and a high R: FR suppresses it. While FR light promotes stem extension, it is also required for rapid, uniform flowering of many long-day plants. We investigated how a new FR filter [creating a FR-deficient (FRd) environment] influenced plug growth and subsequent flowering of pansy (Viola ×wittrockiana `Crystal Bowl Yellow'), petunia (Petunia ×hybrida `Carpet Pink'), impatiens (Impatiens wallerana `Accent Rose'), snapdragon (Antirrhinum majus `Liberty Sca

Abstract:

In this paper, a new structure of Fast Recovery Diode (FRD) and its manufacture methods were investigated. The active region designed by TCAD simulation software could achieve low emitter injection efficiency, and then reduce the peak reverse recovery current, improve the reverse recovery softness and increase working stability. Meanwhile, the effect of the P-body dose and carrier lifetime on the turn-off characteristic of FRD was also discussed. Taking an example of 3300V voltage grade devices for FRD, the reasonable P-body dose and carrier lifetime on the basis of the new structure were conf

It studies the role that is played by feelings of collective victimhood (CV) along with ingroup identity, fraternalistic relative deprivation (FRD), intergroup emotions and relative power in responding to intergroup conflict situations. The results showed that Hindus reported collective victimhood in greater amount compared to Muslims. Muslims felt more FRD than Hindus. Hindus also carried more negative emotions as a cons

We assessed that walnut supplementation (6 weeks) reverted unfavorable changes of the SIRT1/FoxO3a/MnSOD/catalase axis in the heart induced by fructose-rich diet (FRD). Intriguingly, Nox4 was increased by both FRD and walnut supplementation. FRD increased the cytosolic fraction and decreased the nuclear fraction of the uniquely elucidated ChREBP in the heart.

Besides, how to construct a fusion method for the two kinds of uncertain information systematically has been a focus in both academic and applied fields. In this paper, we put forward the concept of level effect function, and analyze the characteristics of a kind of level effect function. Furthermore, we present the fuzzy roughness degree measurement model based on level effect (FRD-BLE), by combining with the roughness measurement meth

Abstract:

For many long-day plants (LDP), adding far red light (FR, 700 to 800 nm) to red light (R, 600 to 700 nm) to extend the day or interrupt the night promotes extension growth and flowering. Blue light (B, 400 to 500 nm) independently inhibits extension growth, but its effect on flowering is not well described. Here, we determined how R-, FR-, or B-deficient (Rd, FRd, or Bd, respectively) photoperiods influenced stem extension and flowering in five LDP species: Campanula carpatica Jacq., Coreopsi ×grandiflora Hogg ex Sweet, Lobelia ×speciosa Sweet, Pisum sativum L., and Viola ×wittrockiana Gams.

Among them, fruit rot disease (FRD) causes serious economic losses that are borne by the growers, making it the greatest yield-limiting factor in arecanut crops. FRD has been known to occur in traditional growing areas since 1910, particularly in Malnad and coastal tracts of Karnataka. Systemic surveys were conducted on the disease several decades ago.

Abstract:

Although creation of layers with different textures in topsoil is known to increase available water holding capacity (AWHC) and plant survival, little is known about associations between the layers and fine root density (FRD) or water consumption. This study investigates the effects of alternating a coarse sand layer over a finer loess layer on alfalfa growth. Soils were packed into 90-cm long columns, either individually or in alternating layers. The three layered soils had layer thicknesses of 11.25, 22.5 or 45cm. Soils were saturated, allowed to drain freely and the AWHC was determined. Alf
