Periodontitis is a chronic inflammatory disease caused by periodontopathic bacteria that affects periodontal support tissues.1 If left untreated,it results in loss of periodontal attachment and alveolar bone *** one-half of adults in the United States older than 30 years have periodontal disease.2 Though the disease is initiated by bacterial infection,it activates host defense systems that eventually lead to the degradation of the *** periodontitis,the disease progress involves further production of pro-inflammatory mediators such as cytokines,proteolytic enzymes like matrix metalloproteinases(MMPs),and their inhibitors.

Dear Editor,The common marmoset(Callithrix jacchus),a small New World monkey species,is considered an ideal non-human primate model for studying the evolution and neural mechanism of vocal behavior due to their rich call repertoire and vocal communication[1-3].Especially,the early vocal development of marmoset monkeys has attracted much attention,because newborn marmosets have been shown to exhibit a vocal development *** two months after birth,marmosets'vocalizations undergo dramatic changes from cries to adult-like mature calls,a process that is influenced not only by inner physical maturation but also by parental care and feedback[4].

Infanticide,killing unweaned offspring in conspecifics,occurs widely among mammals,such as rodents,ungulates,and carnivores,especially in primates(Lukas and Huchard 2014).Such scenarios are often triggered by intruders that have replaced the former dominant males in nonhuman primates(Borries 1997).It has widely been viewed that infanticide is one of the solutions of sexually driven evolutionary selection:males kill infants to end lactational amenorrhea of the victim's mothers,forcing them to return to estrus and providing infanticidal males with the opportunities to sire their new offspring(Hrdy 1979).There is a broad spectrum regarding the patterns and mechanisms causing such events,referring to alternative breeding behaviors and mating systems-monogamy,polyandry,polygyny,and promiscuity(Qi et al.2020).
