I will add photos later. Here then are the generations which are easily discernible even by non-experts. Brass diaphragm rings, no threads in the backplates to screw the capsule into its mount. The U67 prototype, U60, used a clamping ring around the capsule; the first U67 production version was mounted with three tiny pointed set screws threaded into the mounting ring, similar to how M7 capsules were mounted to the U47 capsule mounting ring.

Same as above, but capsule is held in the mount with four M2 slot screws two are screwed into each backplate half 3.

How cancer cells adapt to hypoxia during tumor development remains an important question. The hypothesis tested in the present study was that tumor cell-derived exosome vesicles also known as microvesicles or extracellular vesicles are mediators of hypoxia-dependent intercellular signaling in glioblastoma GBM , i.

In vitro hypoxia experiments and studies with patient materials reveal the enrichment in exosomes of hypoxia-regulated mRNAs and proteins, several of which were associated with poor patient prognosis. We show that cancer cell exosomes mediate hypoxia-dependent, phenotypic modulation of stromal cells in vitro and ex vivo, resulting in accelerated GBM tumor angiogenesis and growth in mice. These data suggest that exosomes constitute potent mediators of hypoxia-driven tumor development, and circulating multiparameter biomarkers of tumor hypoxia.

Conditioned media from normoxic and hypoxic cells were then used to isolate exosomes by differential centrifugation. Both cells and exosomes were lysed in Trizol reagent, and RNA was isolated. Total RNA from all samples four types of samples in three biological repilicates was subjected to genome-wide transcriptional analysis with Illumina HumanHT V3.

How To Date A Neumann U87 Capsule. One capsule has dominated Neumann’s mics over decades: the original K67 and its descendants. Here is a rough.

Suspension mount included. The Neumann U 87 Ai is probably the best-known and most frequently used studio microphone the world over. Its smooth and refined sound is as iconic as its elegant exterior design. The U 87 Ai is the standard microphone for speech and vocals. Three polar patterns plus pad and low cut options make it adaptable to a wide range of applications.

I also have exceptional pre-amps available, for very reasonable prices, including Neve and API. See my other listings! I’m a sound guy. Rent my gear or rent me! Please note that I require photo ID with your address on it if you haven’t rented from me before. I will also ask for a picture of you holding the item you are renting when you collect. This is unfortunately due to having had items stolen in the past.

Does it succeed? Demand for items of classic studio hardware is high and supplies are low, meaning that the originals are out of reach to many home and project-studio owners. This revised capsule was called the K Some feel that in making these modifications, Neumann compromised the sound of the original U87, and there are those who say that the Ai version is slightly harsh or brittle in comparison. Although there are plenty of cheap K67 and K87 replicas available off the shelf, Warm Audio have chosen to produce their own recreation.

The difference was more audible on some sources than others.

G3BP1 knockdown sensitizes U87 glioblastoma cell line to Bortezomib by inhibiting stress granules assembly and potentializing apoptosis. Journal of Neuro-Oncology IF 3. New therapies are currently in development to tackle treatment limitations such as chemotherapy resistance. One mechanism of resistance may be the stress granules SG assembly, a stress-related cellular response that allows cells to recruit and protect mRNAs during stress. Here, we aimed to evaluate the effects of inhibiting the G3PB1 expression in the chemotherapeutical-induced cell death of the U87 glioblastoma cell line.

Caspase-3 activation was evaluated by immunoblotting. The chorioallantoic membrane in vivo assay was used to evaluate angiogenesis. Corroborating this data, we observed increased Caspase-3 activation in the BZM-treated and G3BP1-knocked-down cells when compared to vehicle-treated and scramble-transfected cells. Worth mentioning, the conditioned culture medium of G3BP1-knocked-down BZM-treated cells inhibited angiogenesis when compared to controls.

Topotecan is a topoisomerase topo I inhibitor with promising activity in preclinical studies. We hypothesized that low-dose intratumoral delivery of topotecan would be highly effective for gliomas. Human glioma cell lines U87, U and U displayed different sensitivities to topotecan IC 50 range: 0. The most resistant of the glioma cell lines U87 was implanted stereotactically into the brains of nude rats.

Twelve days later, at which time tumor diameter measured 2 to 2. Animals were sacrificed when signs of deterioration developed, or at 60 days.

The Neumann U87, known for its warm, rich sound and precision engineering, is perhaps the world’s most widely used large diaphragm condenser studio microphone. It is equipped with a large dual-diaphragm capsule with three directional patterns: omnidirectional, cardioid and figure These are selectable with a switch below the headgrille. A 10 dB attenuation switch is located on the rear.

It enables the microphone to handle sound pressure levels up to dB without distortion. Furthermore, the low frequency response can be reduced to compensate for proximity effect.
