Abstract: A packaging cover includes a baseboard and at least one corner structure. The corner structure includes a first region, a second region, a first fold line, a third region, a second fold line, and a fourth region. The first region has a slit, and one of the corners of the baseboard is inserted into the slit. The second region is folded with the first fold line as an axis to be perpendicular to the first region. The third region has a clamping groove. The third region is folded with the second fold line as an axis to be perpendicular to the first region. The fourth region has a fixing part. After the fourth region is folded with the second fold line as an axis, the fourth region is overlapped with the third region, and the fixing part is inserted into the clamping groove.

Abstract: A cushion includes a first member and a second member. The first member includes a first body and at least one first extending portion. At least one sidewall of the first extending portion has a first protruding portion. The second member includes a second body and a plurality of second extending portions. At least one sidewall of each second extending portion has at least one second protruding portion corresponding to the first protruding portion. When the first member and the second member are assembled, the first extending portion and the second extending portions are staggered with each other. When the first member and the second member move away from each other by a predetermined distance, the first protruding portion is clamped to the second protruding portion.

Abstract: An active component of parathyroid hypertensive factor (PHF) which comprises a polypeptide linked to a phospholipid has been identified. The component has activities substantially similar to parathyroid hypertensive factor and therefore is indicated in the control of extracellular calcium uptake, and is related to hypertension and some other diseases in mammals. Method for screening patients for the presence of the circulating factor using antibodies against the component are described. Antagonists of the parathyroid hypertensive factor component have been developed and their use in methods of treating patients with diseases which involve intracellular calcium elevation are also described.

Abstract: A multi-channel transceiver includes a phase-locked loop circuit, a first transmitting channel and a second transmitting channel. The phase-locked loop circuit generates a first clock signal set and a second clock signal set with different frequencies. The first transmitting channel includes a first phase adjusting circuit and a first transmitter. The first phase adjusting circuit receives the first clock signal set and generates a first spread spectrum clock signal with a first SSCG profile. According to the first spread spectrum clock signal, the first transmitter generates a first serial data. The second transmitting channel includes a second phase adjusting circuit and a second transmitter. The second phase adjusting circuit receives the second clock signal set and generates a second spread spectrum clock signal with a second SSCG profile. According to the second spread spectrum clock signal, the second transmitter generates a second serial data.
