Abstract:
An electronic device includes a cabinet and electronic units received in the cabinet. A window is defined between two front columns. Each electronic unit includes a casing, which includes a top plate, a lateral side and a rotator. The lateral side defines an engaging opening therein. The rotator is movably connected to the casing and includes an engaging portion and an abutting portion. The abutting portion extends above the top plate. the engaging portion is received in the casing. When the abutting portion is pushed down, the rotator moves to cause the engaging portion to extend through the engaging opening to engage with the cabinet and to prevent the casing from being pulled out from the cabinet.
Abstract:
An exemplary electronic device assembly includes a cabinet and electronic devices received in the cabinet. The cabinet includes four columns substantially positioned at four corners of the cabinet. A window is defined between two front columns. Each electronic device includes a casing, which includes a bottom plate, a lateral side and an actuator. The bottom plate defines an inserting opening therein. The lateral side defines an engaging opening therein. The actuator movably connects to the casing and includes an engaging portion and an abutting portion. The abutting portion extends through the inserting opening. The engaging portion extends through the engaging opening and engages with one of the columns. When the abutting portion is pushed up, the actuator moves and the engaging portion disengages from the column.
Abstract:
A mounting apparatus is adjusted to selectively mount a first expansion card or a second expansion card. The mounting apparatus includes a bracket, a retaining member fixed to the bracket, and a pivoting member pivotably attached to the retaining member. The pivoting member defines a first locking slot and a second locking slot. The pivoting member is pivotable along a first direction to limit the first expansion card. The pivoting member is pivotable along a direction opposing to the first direction to limit the second expansion card.
Abstract:
A fan module includes a housing, a connecting member, and a fan assembly. The housing includes a bottom wall and a sidewall extending up from the bottom wall. The connecting member is slidably mounted to the bottom wall. The fan assembly includes a frame slidably mounted on the connecting member, and a fan detachably received in the frame.
Abstract:
A hard disk drive holder includes a main body, a spindle mounted to the main body and slidable between first and second positions, a handle rotatably connected to the main body via the spindle, a hook mounted to the handle, and first and second elastic members. The handle includes a locking tongue. The handle moves between closed and opened positions relative to the main body. When the handle is at the closed position, if the spindle is slid from the first position to the second position, the locking tongue gradually extends outside from the main body. When the handle is at the closed position, if the spindle is not at the first position, the hook can hook the main body. The first elastic member biases the spindle to slide to the second position. The second elastic member biases the handle to rotate to the opened position.

Abstract:
Genomic imprinting is a parent of origin-dependent gene silencing that involves marking of alleles in the germline and differential expression in somatic cells of the offspring. Imprinted genes and abnormal imprinting have been implicated in development, human disease, and embryonic stem cell transplantation. We have established a model system for genomic imprinting using pluripotent 8.5 d.p.c. mouse embryonic germ (EG) cell lines derived from an interspecific cross. We find that allele-specific imprinted gene expression has been lost in these cells. However, partial restoration of allele-specific silencing can occur for some imprinted genes after in vitro differentiation of EG cells into somatic cell lineages, indicating the presence of a gametic memory that is separable from allele-specific gene silencing. We have also generated a library containing most methylated CpG islands. A subset of these clones was analyzed and revealed a subdivision of methylated CpG islands into 4 distinct subtypes: CpG islands belonging to high copy number repeat families; unique CpG islands methylated in all tissues; unique methylated CpG islands that are unmethylated in the paternal germline; and unique CpG islands methylated in tumors. This approach identifies a methylome of methylated CpG islands throughout the genome.
Abstract:
The present invention provides a fibrinolytic composition useful as a therapeutic for administration to a patient having a thrombotic occlusion. In one aspect of the present invention, the fibrinolytic composition comprises a reversibly inactivated acidified serine protease substantially free of a plasminogen activator, a low buffering capacity buffer, and optionally, a stabilizing agent. In another aspect of the invention, the fibrinolytic composition of the present invention comprises a reversibly inactivated acidified plasmin substantially free of a plasminogen activator, a low buffering capacity buffer, and optionally, a stabilizing agent.
Abstract:
A single multidirectional chuck for use with a cutting beam such as a fluid jet is disclosed. The single multidirectional chuck includes a first set of cutting slots oriented in a first direction and a second set of cutting slots oriented in a second direction that is transverse to the first direction. One set of cutting slots extends entirely through the chuck so that the cutting beam may pass therethrough. The other set of cutting slots, which are transverse to the first set, only extend partially into the chuck. The partially extended cutting slots each provide a space that leads to a sacrificial member housed with a cavity in the single chuck. During a cutting operation, the cutting beam passes through the partially extended cutting slots and bombards the sacrificial member. The sacrificial member is configured to sacrifice itself in order to protect the structural components of the chuck. The sacrificial member is also configured to temper and redirect the flow of the fluid jet so that it can be exhausted out of the chuck as for example through the fully extended cutting slots.
