Alternative Anesthesia of Neonatal Mice for Global rAAV Delivery in the Brain With Non-detectable Behavioral Interference in Adults.

Viral-transduced gene expression is the current standard for cell-type-specific labeling and cell tacking in experimental neuroscience. To achieve widespread gene expression, a viral delivery method to neonatal rodents was introduced more than two decades ago. Most of those neonatal viral vector injection-based gene transduction methods in mice used deep hypothermia for anesthesia, which was reported to be associated with behavioral impairments.

The effects of neonatal cryoanaesthesia-induced hypothermia on adult emotional behaviour and stress markers in C57BL/6 mice.

Since the early 1930s, deep hypothermia (cryoanaesthesia) has been a useful anaesthetic in several types of surgery on neonatal rodents. Especially against the background of modern techniques in systems neuroscience, the method enjoys again increasing popularity. However, little is known about its effects on the subsequent adult behavioural and physiological profile.

Device for the local radiation of tumor-bearing laboratory rodents.

Since no standard method for reproducibly irradiating local tumors of laboratory rodents exists, the authors designed a device to accurately irradiate rodent tumors. Laboratory personnel can easily assemble this inexpensive device. The new device delivers highly focused treatment and avoids the need for anesthesia and sedation.

Efficacy and tolerability of an aminopterin-albumin conjugate in tumor-bearing rats.

The antifolate aminopterin (AMPT) was developed before methotrexate (MTX), but was not clinically established or generally used due its increased toxicity compared to MTX. Recently, we reported on the increased metabolism of albumin conjugates such as methotrexate-albumin (MTX-SA) in malignant tumors and the feasibility of using albumin as a carrier for drug targeting. Consequently, AMPT was covalently bound to serum albumin (AMPT-SA) at a 1:1 molar ratio.

The RAG 2 mouse model for xenografted human oral squamous cell carcinoma.

Animal tumor models are still essential for the development of new medication and therapy concepts. In the field of human oral squamous cell cancer, there are few reliable xenografted tumor models available. Therefore, during a two-course experiment, we established a new xenografted tumor model of human oral squamous cell cancer.
