Grape seed and skin extract: A weapon in the fight against kidney disease caused by high-fat diets
Researchers examined the effect of GSSE processed from a grape cultivar ('Carignan') of Vitis vinifera from northern Tunisia on rats. Rats were fed a high-fat diet that induced a low-grade reno-lipotoxicity, that is, kidney damage associated with lipids. This was characterized by elevations in plasma urea and protein in the urine. The researchers found increased deposits of triglycerides (TG) (especially saturated fatty acids), increased signs of oxidative stress and depleted copper levels in the kidneys. There was also histological evidence of disturbance in the kidney structure. When the animals received GSSE at 500 mg/kg bw (which corresponds to 35g/day for a 70 kg human adult) along with the high-fat diet there was a partial reversal of the TG deposition as well as the histological damage. The authors suggest polyphenols including resveratrol are likely the components in GSSE responsible for the positive effects. Furthermore the GSSE prevented the oxidative stress and copper depletion.
"In our research, obesity-induced leaky kidney and proteinuria are shown to be prevented by GSSE, which suggests the use of GSSE as a preventive nutriceutical for high-risk patients," said co-author Kamel Charradi, a researcher with the Laboratory of Bioactive Substance at the Center of Biotechnology of Borj-Cedria (CBBC) in Tunisia. This research group has previously published work showing the benefits of GSSE in combating obesity, heart dysfunction, brain lipotoxicity and kidney cancer.....

New chemical probe provides tool to investigate role of malignant brain tumor domains in chromatin structure and regulation
Researchers lead by assistant professor in the lab of Stephen Frye, Fred Eshelman Distinguished Professor in the UNC School of Pharmacy and member of the UNC Lineberger Comprehensive Cancer Center, announced the discovery of a chemical probe that can be used to investigate the L3MBTL3 methyl-lysine reader domain. The probe, named UNC1215, will provide researchers with a powerful tool to investigate the function of malignant brain tumor (MBT) domain proteins in biology and disease.....

High-Fiber Diet Helps Heart Too, Expert Says - Drugs.com MedNews
Eating a high-fiber diet does more than promote digestive well-being; it's also good for your heart, an expert says.
Dietary fiber from fruits, vegetables, whole grains and beans "has
been shown in research to help lower cholesterol," Jody Gilchrist, a
nurse practitioner at the Heart and Vascular Clinic at the University of
Alabama, Birmingham.
"Most nutrition experts say that a person needs at least 25 grams of fiber a day as part of a balanced diet," Gilchrist said. "The American Heart Association recommends that a good rule of thumb is 14 grams of fiber for every 1,000 calories consumed, and at least 10 grams should come from soluble fiber."
Soluble fiber makes you feel full quickly, which helps control how
much you eat. Research has shown that soluble fiber also helps lower
"bad" LDL cholesterol by interfering with how the body absorbs
cholesterol from foods.

Positive health indicators associated with avocado consumption
We know that avocado (Persea americana) is a tree native to Central Mexico, classified in the flowering plant family Lauraceae along with cinnamon, camphor and bay laurel. Avocado or alligator pear also refers to the fruit (botanically a large berry that contains a single seed) of the tree.
Avocados are commercially valuable and are cultivated in tropical and Mediterranean climates throughout the world. They have a green-skinned, fleshy body that may be pear-shaped, egg-shaped, or spherical. Commercially, it ripens after harvesting. Trees are partially self-pollinating and often are propagated through grafting to maintain a predictable quality and quantity of the fruit.
The fruit of horticultural cultivars has a markedly higher fat content than most other fruit, mostly monounsaturated fat, and as such serves as an important staple in the diet of various groups where access to other fatty foods (high-fat meats and fish, dairy products, etc.) is limited.
A ripe avocado yields to gentle pressure when held in the palm of the hand and squeezed. The flesh is prone to enzymatic browning; it turns brown quickly after exposure to air. To prevent this, lime or lemon juice can be added to avocados after they are peeled.

Tranylcypromine may also hold promise in treating sickle cell disease
In continuation of my update on Tranylcypromine
An antidepressant drug used since the 1960s may also hold promise for treating sickle cell disease, according to a surprising new finding made in mice and human red blood cells by a team from the University of Michigan Medical School.
The discovery that tranylcypromine, or TCP, can essentially reverse the effects of sickle cell disease was made by U-M scientists who have spent more than three decades studying the basic biology of the condition, with funding from the National Institutes of Health.

Meloxicam recognizes and treats osteoarthritis in cats
Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and fever reducer effects. It is a derivative of oxicam, closely related to piroxicam, and falls in the enolic acid group of NSAIDs. It was developed by Boehringer-Ingelheim.

Resistant starch kills pre-cancerous cells and reduces inflammation
Resistant starch (RS) is starch and starch degradation products that escape digestion in the small intestine of healthy individuals. Resistant starch is considered the third type of dietary fiber, as it can deliver some of the benefits of insoluble fiber and some of the benefits of soluble fiber.
Some carbohydrates, such as sugars and most starch, are rapidly digested and absorbed as glucose
into the body through the small intestine and subsequently used for
short-term energy needs or stored. Resistant starch, on the other hand,
resists digestion and passes through to the large intestine where it acts like dietary fiber.

New Antibiotic May Treat Skin Infections in Shorter Time - Drugs.com MedNews
Torezolid (also known as TR-701 and now tedizoli) is an oxazolidinone drug being developed by Trius Therapeutics(originator Dong-A Pharmaceuticals) for complicated skin and skin-structure infections (cSSSI), including those caused by Methicillin-resistant Staphylococcus aureus (MRSA).
