Menstrual Cycle

Checkpoint kinase 1 CHK 1

Progression through the cell cycle is monitored by surveillance mechanisms known as cell cycle checkpoints. Dysfunction in cell cycle checkpoints leads to genomic instability and contributes to tumo...

Polo like kinase Plk 1

Polo-like kinase (Plk) is an important cell cycle regulatory kinase that has been implicated in a multitude of cell cycle events. Plks form a family of four different proteins that regulates many as...

Novel Mitotic Kinase Inhibitors

Mitosis, a central event in tumor growth, is highly regulated to ensure accurate and equal segregation of genetic materials from parent cells to daughter cells. Main effectors of this process are mi...

Bulimia Nervosa

Bulimia is an illness characterized by the cycle of binging on food, guilty feelings and resultant purging (vomiting or laxative abuse) to counteract the previous binge. It is much more common in yo...

Aluminum could give a big boost to capacity and power of lithium-ion batteries

One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle—sometimes doublin...

Freeze–thaw cycles as drivers of complex ribozyme assembly

During the early stages of life on Earth sophisticated RNA catalysts must have formed from simple precursors. Here it is shown that freeze–thaw cycles can drive the assembly of complex RNA polymeras...

Multi-omics of permafrost, active layer and thermokarst bog soil microbiomes

Over 20% of Earth’s terrestrial surface is underlain by permafrost with vast stores of carbon that, once thawed, may represent the largest future transfer of carbon from the biosphere to the atmosph...

Design of experiments reveals critical parameters for pilot‐scale freeze‐and‐thaw processing of L‐lactic dehydrogenase

Freezing constitutes an important unit operation of biotechnological protein production. Effects of freeze‐and‐thaw (F/T) process parameters on stability and other quality attributes of the protei...

Repeated use of antibiotics may increase risk of type 2 diabetes

Repeated use of some types of antibiotics may put people at increased risk of developing type 2 diabetes through potentially altering their gut bacteria, according to a large observational study.

Repeated use of antibiotics linked to diabetes risk

Repeated use of some types of antibiotics may put people at increased risk of developing type-2 diabetes by possibly altering their gut bacteria, according to a large observational study published tod...

Promising New Treatment Emerges For Deadly C. difficile Colitis

A new Phase 2 pilot study shows that giving spores of a non-toxic C. difficile bacteria by mouth is effective in stopping repeated bouts of C. diff infection, a major complication of hospitalization. ...

Trajectories of cell-cycle progression from fixed cell populations

Cycler constructs a trajectory of cell-cycle progression from fixed images of cells enabling the correlation of an individual cell's position in the cell cycle with multiple cellular readouts.

Effect of Freeze/Thaw Cycles on Several Biomarkers in Urine from Patients with Kidney Disease.

Urine samples were collected from eleven randomly selected patients with kidney disease, including diabetic nephropathy, chronic nephritis, and nephritic syndrome. Urine samples were treated with one ...

Genes Upregulated in Winter Wheat (Triticum aestivum L.) during Mild Freezing and Subsequent Thawing Suggest Sequential Activation of Multiple Response Mechanisms.

Exposing fully cold-acclimated wheat plants to a mild freeze-thaw cycle of -3°C for 24h followed by +3°C for 24 or 48h results in dramatically improved tolerance of subsequent exposure to sub-freezi...

High Methylmercury in Arctic and Subarctic Ponds is Related to Nutrient Levels in the Warming Eastern Canadian Arctic.

Permafrost thaw ponds are ubiquitous in the eastern Canadian Arctic, yet little information exists on their potential as sources of methylmercury (MeHg) to freshwaters. They are microbially-active and...

Pre-Analytical Sample Quality: Metabolite Ratios as an Intrinsic Marker for Prolonged Room Temperature Exposure of Serum Samples.

Advances in the "omics" field bring about the need for a high number of good quality samples. Many omics studies take advantage of biobanked samples to meet this need. Most of the laboratory errors oc...

New extender for cryopreservation of siberian sturgeon (Acipenser baerii) semen.

The goal of this study was to develop a simple glucose-methanol extender for cryopreservation of Siberian sturgeon (Acipenser baerii) semen. Semen quality was assessed by determining post-thaw sperm m...
