Multiple Renal Tumours: One Step Beyond Conservative Management

[Disease management programs in heart failure: one step beyond pharmacology].

Despite pharmacological advances, both mortality and the incidence of hospital admissions are high for heart failure. As with many other chronic diseases, the findings of clinical trials are difficult to implement due to lack of adherence to treatment, frequent comorbidities not considered in clinical trials, and health systems’ typical focus on acute diseases. Public health systems usually pay...

Developmental Biology: Cell Intercalation One Step beyond

Formation of the primitive streak, the equivalent of the blastopore, is a critical step during the early development of amniote embryos. Medio-lateral cell intercalation and the planar cell polarity pathway play a role during this earliest step of gastrulation in the chick embryo.

Conservative management of chronic renal failure.

Failing kidneys can play havoc with other parts of the body. Specific treatment of these associated problems may help ward off uremia and preserve whatever renal function remains. Sodium levels may drop if too much water is mistakenly given to counteract kidney failure. Hyperkalemia can lead to cardiac arrest if potassium levels aren't reduced without delay. Acidosis also may reach life-threate...

One step beyond: Different step-to-step transitions exist during continuous contact brachiation in siamangs

In brachiation, two main gaits are distinguished, ricochetal brachiation and continuous contact brachiation. During ricochetal brachiation, a flight phase exists and the body centre of mass (bCOM) describes a parabolic trajectory. For continuous contact brachiation, where at least one hand is always in contact with the substrate, we showed in an earlier paper that four step-to-step transition t...
