Pregabalin, chemical name (s) - 3-aminomethyl-5-methylhexanoic acid, molecular formula c8h17no2, is an antiepileptic drug, mainly for the treatment of postherpetic neuralgia. The appearance and properties of pregabalin are white or almost white crystalline powder γ- GABA analogues, similar to gabapentin in structure and function, have antiepileptic, analgesic and anxiolytic activities. The antiepileptic mechanism of pregabalin remains unclear. In laboratory studies, pregabalin has anticonvulsant activity in various epilepsy models; The activity spectrum of animal model was similar to that of gabapentin, but the activity of pregabalin was 3-10 times higher than that of gabapentin.
Pregabalin is an antiepileptic drug, is mainly used in the treatment of postherpetic neuralgia.

Serrata Crab Harvesting Clever Way
The green crabs in the intertidal zone should be collected promptly, using effective trapping methods to capture both large and small crabs, ensuring a balanced harvest that maximizes economic returns. September marks the mating season for blue crabs, making it a critical time for harvesting. Male crabs, after multiple mating sessions, tend to lose weight significantly, which reduces their market value and can lead to high mortality rates. Similarly, female crabs, once they have mated, need proper care. After 30 to 40 days of feeding, they develop into mature crabs. However, if left too long, over-ripening may occur, leading to poor quality and reduced value. Additionally, as sea temperatures begin to drop, green crabs become harder to raise during winter, so timely collection is essential. Most aquaculture operations aim to complete the harvest of blue crabs in ponds by the end of October.
There are several effective methods for capturing green crabs:
(a) **Light Trapping**: Blue crabs are known to climb the edges of pools or tidal areas at night. Using lights can help attract them, making it easier to catch them with nets.
(b) **Dry Pool Trapping**: This method involves draining the pond partially and using manual techniques to collect crabs. It's an old but efficient approach.
(c) **Manual Catching**: This traditional technique requires skill and patience. Crabs are caught by hand, which minimizes damage, but it’s physically demanding and not suitable for large-scale operations.
(d) **Netting**: Using crab nets is a common practice. It saves time but can cause injuries to the crabs if not handled carefully.
Once captured, blue crabs must be bundled securely to prevent them from biting each other. During hot summer months, they should be stored in cool and humid environments. In colder weather, covering them with water-soaked grass helps maintain moisture and protects them from the cold. Proper handling and storage are crucial to maintaining the quality and marketability of the crabs.
Xylazine hydrochloride has analgesic, sedative and central muscle relaxation effects. Alpha Lipoic acid has Antioxidant capacity. It can remove the active oxygen components that cause skin aging, especially for dark circles, wrinkles and spots. In addition, it can strengthen the metabolic function, improve the blood circulation of the body, improve the dullness of the skin, and reduce the pores. Gabapentin Powder is a white to grayish white crystalline powder with stable chemical properties at normal temperature and pressure. It is an additional treatment for epilepsy patients with localized seizures which can not be satisfactorily controlled or tolerated by conventional antiepileptic drugs and epilepsy patients with localized seizures and then generalized. Berberine hydrochloride is mainly used in the treatment of gastroenteritis, bacillary dysentery and other intestinal infections, eye conjunctivitis, suppurative otitis media, etc. Recently, it has been found that this product has blocking effect α- Receptor, antiarrhythmic effect. NMN Powder (nicotinamide mononucleotide): full name[ β- Nicotinamide mononucleotide "is a kind of naturally occurring biologically active nucleotide. The decline of NAD in aging process is considered to be the main cause of disease and disability, such as hearing and vision loss, cognitive and motor dysfunction, immune deficiency, arthritis, metabolic disorder and cardiovascular disease caused by autoimmune inflammatory reaction disorder. Therefore, NMN supplementation can increase the content of nad+ in vivo, thus delaying, improving and preventing aging related phenotypes, or age-induced metabolic disorder, aging diseases, etc.
