Comprehensive Laboratory Meeting Notes: Molecular Research, Clinical Procedures, and Long-Term Strategic Goals

Strategic Navigation of Academic and Professional Environments

  • Academic Survival Theory: A core principle shared for success in academia is to "fly under the radar."     - This approach implies remaining largely invisible regarding administrative politics to avoid unnecessary duties or public speaking requirements.     - The primary benefit Cited is the ability to focus on research and laboratory work without distraction.     - The speaker notes an upcoming meeting with the President of the university, acknowledging it as "good news" despite not knowing the specific agenda.

Financial and Administrative Responsibilities

  • University Cash Handling: High priority is placed on depositing university funds immediately with Elvira.     - The speaker expresses a strong personal dislike for being responsible for "university cash" due to the liability and oversight involved.

  • Animal Sales: Discussion regarding the sale of three animals (rams) to Rams.     - Financial details: Money for two animals was received; the third may receive funding from another source.

Molecular Biology Research Updates and Equipment Requirements

  • cDNA Synthesis and RNA Quality:     - Caroline reported a poor cDNA run despite good RNA quality.     - The target gene for the run was GAP.     - There is an urgent need for a new cDNA kit as current supplies for PCR are high, but cDNA-specific kits are depleted.

  • Laboratory Supply Shortages:     - Pipette Tips: Immediate need for 20μl20\,\mu{l} and 200μl200\,\mu{l} filtered tips.     - Non-filtered vs. Filtered: There are current supplies of 200200 non-filtered tips, but filtered ones are required for current protocols. Existing tips do not fit the pipette with the green tip.     - Parafilm: The lab is currently out of Parafilm, and a request was made to purchase a dedicated stock for the lab.

  • Antibody Homology Analysis:     - Comparison was conducted between conjugated and human TIM 4 antibodies.     - Findings: The conjugated version showed higher homology.     - A sheep-specific antibody was also mentioned as a third comparison point.     - Caroline is tasked with sending the exact percent homology data to the supervisor.

Experimental Case Studies and Emerging Literature

  • Current Trial Status: The group discussed a system approach involving 33 control animals and 33 treated animals.     - These animals were maintained through at least 55 days/treatments before being euthanized for tissue harvesting.     - Confirmation is needed to see if the Kupffer cell approach or the "system approach" is functioning as intended.

  • T-Cell and Obesity Research: Discussion centered on a specific paper regarding CD4 positive T-cells and "obesity memory."     - Phenomena: In individuals with extreme obesity who lose weight, CD4 positive T-cells were found surrounding and inside fat cells.     - Mechanism: The cytokine profile of these cells likely facilitates regaining weight; the cells appear to sense nutrient status.     - Significance: These cells are also vital for pregnancy recognition. The lab is considering if they are "barking up the wrong tree" with Kupffer cells and should instead investigate these T-cells or a combination of both.

  • Future Methodology: Liver Biopsies:     - The lab proposes isolating immune cells directly from liver biopsies in sheep.     - Plan: Perform biopsies, allow healing, and then perform flow cytometry on the isolated cells.     - Economic Incentive: This allows the research to continue while still being able to sell pregnant ewes later (referred to as a "money bag").

Departmental Clinical Tasks and Scheduling

  • Vasectomy Procedures:     - Tyler requested vasectomies for 33 more billies (goats) and 11 ram for the upcoming breeding season.     - Semen Testing: Scheduled for next Wednesday with Eric to confirm the success of previous procedures using a scope to check volume and cell presence.

  • Surgical Schedule:     - May 19 (Tuesday): Identified as the primary window for surgery (vasectomies).     - July 22: Start date for the first round of AI (Artificial Insemination). The vasectomized males must be cleared (electro-ejaculated) and ready by this time.     - July 14: Target date for having the males "squared away" and sterile for at least 88 weeks.

  • Institutional Approvals: There was a discussion regarding IACUC approval for performing repeat surgeries on the same animal if a vasectomy fails. Concerns were raised about whether a second surgery on the same site would be permitted.

  • Anesthesia Logistics: Review of the gas machine operation and filling requirements for surgeries with Dr. Ashley.

Applied Reproductive Technology Course Development

  • Course Concept: Proposal for an Applied Repro Course or Applied AI Core to be launched next spring.     - Curriculum: Includes semen handling, cell counting, BSEs (Breeding Soundness Exams), dilution, freezing straws, and AI techniques.

  • Financial Investment: Realizing the course requires a significant initial investment, estimated near $250,000\$250,000.     - This includes buying cows and feed (which Tyler offered to float).     - The risk involves market fluctuations when selling the animals later.

Data Analysis and Grant Preparation

  • Grant Deadline: The grant must be completed by July. This necessitates having "preliminary data" and successful cDNA results by early summer.

  • Arturo’s Test Plate Protocol:     - Treatment applied to a test plate, with readings scheduled for 05:3005:30 and 06:0006:00.     - Setting: Alimar blue setting on the reader.     - Reading Intervals: 1515, 3030, 6060, 120120, and 240240 minutes.

  • Quina’s Data Management:     - RNA work is ongoing.     - Data Cleaning: Removing data points with values less than 33 to improve summary aesthetics.

  • Critical Questions for Grants:     - Immunofluorescence (IF): Visual proof of the system working.     - PCR: Molecular proof of efficacy.     - CBC Data: Complete Blood Count metrics.     - Progesterone (P4P4): Checking if steroid metabolism was altered. Results are pending review by Dr. Gifford.

Laboratory Inventory and Material Orders

  • High-Expense Items: Arturo noted the need for more plates (approximately 2525 special plates).

  • General Supplies:     - Gloves: Large quantities are needed for upcoming surgeries.     - Cell Culture: T75 flasks (2020 needed), T125 flasks, and freezing vials.     - Surgical Prep: Sutures, needles, packs, gauze, and sterile drapes/towels.

Questions & Discussion

  • Question: What happens if a semen test shows a vasectomy didn't work?     - Response: The team would have to consult Dr. Ashley regarding the possibility of a "re-surgery," though this may conflict with IACUC protocols.

  • Question: Are there trends in Artificial Insemination equipment for sheep?     - Response: It is currently very difficult to find Transcervical AI guns. Most practitioners use Laparoscopic AI or the "Splash" method.

  • Anecdote regarding AI Equipment: The speaker recounted a time in the Navajo Nation (Arizona) where they only had a half cccc gun but quarter cccc straws. They improvised a plunger using a small marker flag from road construction, which fit the straw perfectly.
